Because of an accidentally double booking Birgit cleaned up her whole own apartment to let us stay in there. The next day she moved our luggage to the apartment which is described above. It is a lovely, spacious, light and clean apartment. We stayed with 8 friends and we had enough space. The communication with Birgit was easily, we had enough keys and because of the hassle of the double booking we didn't have to pay for one person extra.
Prenzlauer Berg is a nice neighbourhood with cosy bars and restaurants close by. The U-bahn and tram are also close to the apartment from where you can easily get to the rest of the city. I would recommend this apartment when you are visiting Berlin!
