For this project, I was interestested in using the Airbnb data from a city of Brazil, country where I currently reside. The only data available for Brazil was from Rio de Janeiro.
The dataset used for this project is available at: http://insideairbnb.com/get-the-data.html
Once I used the Airbnb platform to search for house/apartments to rent in Rio and I notice a huge price difference between them, mainly between different neighborhoods. I used this fact as a starting point in my project.
