I’ve stayed a week in this nice apartments on the first floor in a cozy district. Good connection to u-bahn and s-bahn, 15 minutes walk from Central bus station. My bus arrived early in the morning and it was very convenient to leave the bags until check-in in the the hallway. Prompt support from Frank in case any questions. Wi-fi was quick and stable except one day, and Frank tried to resolve the issue immediately, but may be the reason was +37 outside. By the way it didn’t fill as hell these days in the room. Various cafes and restaurants nearby, 2 ReWe, one of which is till 00:00 AM. 15 minutes walk to charming castle Charlottenburg where you can walk with kids or jog. I was lucky with neighbors, it was quiet and clean all the time. In summary, everything was fine. Thanks, Frank.
