The booking and interaction was smooth and clear. When i arrived at the apartment Patrizia, a friend of Alan and Kasia, was waiting for me and explained everything. the apartment was clean and nice and the location is excellent - center of Prenzlauer Berg, less than a minute from the S and U bhan - super conviniet.
The only point i liked less was the fact that this is a rental apartment and not someone's real home, hence lacking personality and is not the same experience as i had with previous airbnb stays.
But overall - i very nice experience.
