sigrid was really nice and easy going. the flat is modern, spacious and light. for us as a family with two kids and a stroller the elevator was more than useful. the kitchen was easy to use, modern and fully equiped. the apartment is in a quiet part of kreutzberg yet it's close to buses, the subway, bars, cafés and good restaurants. a nice bonus was the sound system.
we enjoyed our stay and would recommend anyone going to berlin to stay in sigrids place.
