I stayed a month with my girlfriend in the apartment. The place is very quiet, the bed is comfortable, it's very clean and the kitchen has every appliance you may need. Bigger than we imagined by the photos. It's a good location, close to the subway (S1 is at the corner, U7/S2/S26 trains 5 min walk) and to main points of the city, but there's only a few places to have lunch or drinks around. It's a residential area so there's not a lot of bars around like in other neighborhoods in center of Berlin. We also loved the privacy we had there. We highly recommend it.
