Baerbel’s place was very clean. It is inside her house and upstairs. The only thing separating the apartment from the rest of the house is a flimsy screen door. Also it is about a 45-50 minute tram/train/bus ride into the center of Berlin where all of the attractions are. Otherwise a very nice stay. Baerbel gave us many suggestions and provided us with new clean towels a few times during our stay.
