Rainer's loft became our little home during our time in Berlin. It's a bit of a trek to the 5th floor but once you get up there it's nice and peaceful. Everything was clean and worked as described. Rainer's communication was flawless. The area is pretty grungey but has lots of little cool restaurants, bars and galleries if you know where to look (be sure to check out Ranier's list of things to do). All in all, we'd definitely recommend Rainer's place, as long as you're not too old to climb that many stairs :)
