Love the area, Kreuzberg is such a great place to stay and from Ralph's flat you really can walk to all the great bars and restaurants that are in the area. Flat was absolutely beautiful, nice and big but not cold at all which was surprising! We stayed at the end of October and didn't even need the heating on. Ralph was also very flexible with our check-out time which was great, I guess we were lucky that no-one else was moving in that day.
