It’s was a pleasure to stay in Rainer’s apartment. Interior was nice and cozy. We had everything that we needed - from blankets to coffee. Location is near U-Bahn and S-Bahn stations, so it took us about 20 minutes to get to city center.
However, there were problems with hot water (Rainer helped us to fix them) and it was cold in the apartment - heating didn’t work.
Despite that, we really enjoyed our stay :)
