I enjoyed my time at Barbara's place. She's a great host, I felt welcome. The room looks bigger on the photos, I was very happy about that! The closest metro station is Hallesches Tor (~3 minutes away by walking) and it's 2 stops away from the center of Kreuzberg. The Kreuzberg neighborhood has very nice bars and restaurants. Checkpoint Charlie and the Jewish Museum are also close (~10 mins walking) to Barbara's place.
