I had a very enjoyable stay at Britta's arb&b. It is more like a hotel room than someones apartment, but that being said, it is very clean and quiet and is well equipped . Check-in is easy and Britta is very quick to respond to any questions or concerns. The apartment is very close to the U-bahn so getting around on public transportation is super easy. Kreuzberg is a great walking neighborhood, and the arb&b is very close to restaurants and shopping.
