Andrew's place is incredible, the pictures don't do it justice. It's very big and as the others have stated, the location cannot be beat. I'd highly recommend staying here when you come to Berlin. The neighborhood has so many great cafes, restaurants and bars and you can walk everywhere. Myself and two friends had a great time and the host is super kind and friendly -- they even gave us a bunch of great recommendations that we're awesome. I'll definitely stay here again when I come to Berlin!
