I slept well the 3 nights I was there. The backyard is quiet, the room is warm, there is a really nice bathroom. And Jörg is a man with whom to discuss issues relevant to the (political) heart. Unfortunately too brief time to do so. Maybe next time, Jorg?
Easy access to U-Bahn U7 access to the whole of Berlin, as well as going directly to end station Rubow, where the X3 from Schönenfeldt arrives at and departs from. Plenty of cheap eateries in the area. Turn left from Reutersstrasse onto Karl Marx Strasse and find a small bakery on the right hand side of the road, which opens at 5.30 in the morning and has (not amazing but fairly priced) cheap food and pleasant service.
