Carmen's place was one of the most unique accommodations we ever found trough AirBnB and we enjoyed our stay there. It has a very urban, rough charm. Carmen describes the character very accurately on her site. The place is well equipped, clean and very quiet, except for the occasional train passing, which didn't bother us at all. Unfortunately the weather wasn't warm enough to enjoy the lovely courtyard. We found it a bit creepy to walk around at night, when the immediate neighbourhood is deserted, and decided to take a taxi, which are affordable in Berlin. Friedrichshain, about 15 minutes walk from Carmen's place, is a trendy, lively area with many good cafés, restaurant and bars as well as good public transport to all other parts of Berlin.
