I enjoyed my stay at Heike & Heinrich’s place. The studio is simple, but you've got basically anything you need. The location is amazing, with a short walk to a S-Bahn station, and I was so thankful that I was able to take the S-Bahn when BVG put a strike and almost all the buses/trams and U-Bahn was not available on Apr. 1 (hahaha). I'd definitely recommend staying here!
