The apartment is cozy, bright, perfectly clean and big enough for a couple; the position is very convenient if you want to visit the main hotspots of Berlin because in front of the house there’s a stop of the U6 (which links you also to the nevralgic S Bahn station of Friederichstraße).
Ruth was very kind welcoming us, but she only speaks german and spanish, the thing was not a problem for us because she was able to understand many italian words, but it could be for other guests.
