We had a fantastic stay at Anna's apartment. Our group was three adults and two small children. The space was really perfect for us and very child-friendly (so many nice toys for them to play with!!). The couple stayed in the bedroom with the children; the single adult stayed in the living room on the couch which is convertible to a bed. The convertible bed is very comfortable for a single person; I think it would be less comfortable for a couple. Overall a beautiful, well decorated and well-appointed space. Wonderful for families, very hip neighborhood. Even without kids would be a great low-key, relaxed place to stay in Berlin.
