INTRODUCTION Airbnb has transformed the way people travel, offering a unique platform where hosts can rent out their homes and travellers can find accommodations that fit their needs and budget. In Munich, Airbnb has become a popular choice for tourists seeking a more personalized and local experience. The city offers a wide range of accommodations on Airbnb, from single rooms to entire homes. The types of accommodations offered on Airbnb in Munich are diverse, including Entire homes/apartments, Private rooms, and Shared rooms. Each type of accommodation offers a different experience and price point, catering to a wide range of traveller needs. However, the growth of Airbnb in Munich also raises important questions about its impact on the local housing market, neighbourhood dynamics, and city regulations. In this presentation, we will analyse these issues, using data from Inside Airbnb to analyze the Airbnb landscape in Munich. We will explore the average cost per night, the distribution of listings across the city, the influence of reviews on price, and more. The insights gained from this analysis will help inform policies and interventions to ensure the sustainable development of the city and social justice for local residents. DATA CLEANING AND PRE-PROCESSING The first step in our analysis was to clean and pre-process the data. This is a crucial step as it ensures the quality and reliability of our findings. We started by importing the data from the listings.csv file, which contains detailed information about each Airbnb listing in Munich. We then performed an initial exploration of the data to understand its structure and identify any potential issues. This included checking for missing values, duplicate entries, and inconsistent data types. We found that some columns, such as 'price', contained non-numeric characters, which required cleaning. We removed these characters and converted the column to a numeric data type. We also found that some columns had missing values. For example, the 'reviews_per_month' column had missing values for listings with no reviews. We filled these missing values with zero, assuming that no reviews mean no reviews per month. We faced a few challenges during this process. For instance, the 'neighbourhood' column had many unique values, making it difficult to analyze at a granular level. To address this, we decided to focus our analysis on the 'neighbourhood_cleansed' column, which provides a more general view of the neighbourhoods in Munich. Despite these challenges, we were able to clean and pre-process the data effectively, setting a solid foundation for our analysis. AVERAGE COST AND TYPES OF ACCOMMODATION One of the key aspects we analysed was the average cost per night for each type of room offered on Airbnb in Munich. Our analysis revealed that the average cost per night varies significantly depending on the type of room. Entire homes/apartments tend to be the most expensive, followed by private rooms and then shared rooms. We also calculated a 95% confidence interval for these estimates to provide a range in which we are confident the true average cost lies. This helps account for variability in the data and provides a more robust estimate. In terms of residential (i.e., home-based) accommodation, we conducted one-way ANOVA test and our analysis showed that these tend to be cheaper than hotel rooms. This is likely due to the fact that residential accommodations often do not offer the same level of amenities or services as commercial accommodations. (Appendix 1) However, it's important to note that there is still a wide range of prices within each type of accommodation. Factors such as location, size, and quality of the listing can all influence the price. Out insights can help inform policies aimed at regulating short-term rentals and ensuring affordable accommodation options are available for visitors to Munich. DISTRIBUTION OF LISTINGS AND COST DIFFERENCE Our analysis also explored the distribution of Airbnb listings across different neighbourhoods in Munich. We found that the neighbourhoods with the most listings are Ludwigsvorstadt-Isarvorstadt, Maxvorstadt, and Au-Haidhausen. These areas are popular due to their central location and proximity to tourist attractions. In terms of cost, the most expensive neighbourhoods to stay in are Altstadt-Lehel, Ludwigsvorstadt-Isarvorstadt, and Schwanthalerhöhe. These areas are known for their high-end accommodations and prime locations. When looking at residential listings, we found that they are most prevalent in Ludwigsvorstadt-Isarvorstadt, Maxvorstadt, and Au-Haidhausen. This suggests that these areas are popular for home-based accommodations. We also analysed the cost difference between staying in the city centre districts and further afield. Our analysis showed that accommodations in the city centre tend to be more expensive than those in outlying areas. This is likely due to the higher demand for accommodations in central locations. (Appendix 2) These insights can help inform policies aimed at managing the distribution of short-term rentals across the city and ensuring a balance between tourist accommodations and residential housing. INFLUENCE OF REVIEWS ON PRICE We also investigated the relationship between review scores and the price charged per night. Our analysis revealed a positive correlation between review scores and price. This suggests that listings with higher review scores tend to charge higher prices. However, the correlation was not very strong, indicating that while reviews may have some influence on price, they are not the only factor. Other factors such as location, type of accommodation, and amenities offered likely also play a significant role in determining price. The trend line appears to be significant with every 1 unit increase in review score leading to 9.96 euros increase in the price. (Appendix 3) It's also worth noting that the relationship between reviews and price may not be causal. It could be that higher-quality (and thus more expensive) listings are more likely to receive higher review scores, rather than higher review scores leading to higher prices. Despite this, reviews are still an important aspect to consider as they can impact a guest's decision to book a particular listing. Listings with higher review scores may be more appealing to guests and could potentially command higher prices as a result. Another factor that might influence the price is number of reviews but it appears to have significant relationship but increase in reviews appears to show a negative impact on pricing. (Appendix 4) SUPERHOSTS VS. ORDINARY HOSTS Another aspect we explored was the difference between superhosts and ordinary hosts. Superhosts are experienced hosts who provide a high level of service, and they are recognized by Airbnb with a special status. Our analysis showed that superhosts tend to have similar variations in the price as that of ordinary hosts. We also found that superhosts are more evenly distributed across the city, while ordinary hosts are more concentrated in certain neighbourhoods. This could suggest that superhosts are more likely to offer accommodations in a wider range of locations. (Appendix 5) In terms of price, there was not a significant difference between superhosts and ordinary hosts. This suggests that while superhosts may provide a higher level of service, they do not necessarily charge higher prices. Based on these findings, it could be beneficial to support superhosts as they contribute to a high-quality, diverse range of accommodations across the city. However, it's also important to ensure that all hosts are meeting certain standards to ensure a positive experience for guests. MULTIPLE PROPERTY OWNERS We also conducted an analysis to identify hosts who offer multiple properties on Airbnb. Our analysis revealed that a significant number of hosts in Munich offer more than one property. These hosts tend to have a higher number of total listings and higher review scores compared to hosts who only offer one property. We found that multiple property owners are more prevalent in certain neighbourhoods, suggesting that these areas may be more affected by the short-term rental market. The presence of multiple property owners can have various effects on local residential property markets. On one hand, it can increase the supply of short-term rentals and potentially drive down prices. On the other hand, it can also reduce the supply of long-term housing and drive up rents, particularly in neighbourhoods where multiple property ownership is prevalent. These findings highlight the need for policies that balance the benefits of short-term rentals with the need to maintain affordable housing options for residents. This could include regulations on the number of properties a single host can list or measures to encourage the listing of unused properties.

Airbnb can significantly boost Munich's economy by increasing tourism, stimulating local businesses, and providing additional income for hosts (Mangi et al., 2020). However, Airbnb's growth can lead to social justice concerns such as increased housing prices, reduced long-term rentals, and neighbourhood character changes, as highlighted in studies like Leyk et al. (2020). The impact of urban development on ecosystem services (Yu et al., 2022) and the role of urban green spaces in maintaining habitat connectivity (Nguyen et al., 2020) are additional factors to consider when assessing Airbnb's sustainability in Munich. Policy measures are needed to manage these challenges and ensure Airbnb's benefits are equitably distributed. This could involve listing regulations, affordable housing support, and initiatives to distribute tourism benefits city-wide. CONCLUSION & RECOMMENDATIONS Our analysis of Airbnb data for Munich has revealed key insights into the city's short-term rental market. We found significant variations in average nightly costs based on room type and location, with residential accommodations generally cheaper and city centre locations more expensive (Mangi et al., 2020). Review scores influence price, but other factors such as location, accommodation type, and amenities also play a significant role (Leyk et al., 2020). Super hosts tend to have more listings and higher review scores, but not necessarily higher prices. The presence of hosts offering multiple properties, especially in certain neighbourhoods, could impact local residential property markets, potentially increasing short-term rentals and driving up rents (Nguyen et al., 2020). Balancing Airbnb's economic benefits with social justice needs is crucial for sustainable urban development. This may require listing regulations, affordable housing support, and initiatives to distribute tourism benefits city-wide (Yu et al., 2022). Based on these findings, we recommend further research on Airbnb's impact on Munich's housing market and community, and consideration of regulations to manage short-term rentals growth and ensure equitable benefit distribution.
