I know Berlin well and this was a very good place to stay. Kitchen well-equipped, amazingly quiet and spacious, and the beds very comfortable. The location is great between Sudkreuz and Julius Leber Brücke stations so it is easy to get to places and good for a quiet drink in a couple of local bars on the walk back. If you're into darts I'd recommend The Scotsman! The immediate area is residential but there are plenty of places to shop or good cafes on Hauptstrasse or Akazien Str. about 5 minutes walk away. (And thanks to Heiner for being so friendly.)
