Very nice, small apartment in a perfect location. Good access to two metro stops, lots of cafes, bars, etc. Key pick up was easy, no problems with the rules, etc. Apartment was extremely clean and well equipped. Bed was better than fine. The only thing I'd 'warn' people about is that this doesn't feel like a 'home' at all, but I really don't mind and you shouldn't, either. It's a great place to base yourself in Berlin.
