Carolina's apartment is simply lovely. The place is well furnished and has everything you need for both short and long stays. The apartment has a very quiet neighbourhood and it is well connected through trams and S-Bahn. It is also well located in one of Berlin's warmest "Bezirke", close to nice cafes, shops, supermarkets and the weekly market. Communication with Carolina were always smooth and quick. I will definitely come back for my next stay in Berlin!
