Hello, I am looking for free available data for my future research about sharing economy. I would like to know some data (occupancy, ADR, Demand, etc.) about AirBnB in Europe (primarily in Germany, Hungary and Czech Republic). I know that AirDNA can provide those data, but their prices are high. Do you have any other source for data between 2012 - 2017 ? Thank you for your answer(s).
