We enjoyed our stay a great deal. The building is on a small park, Helmholtzplatz, that has a scruffy charm. There’s a playground filled with small children and in the center some ping pong tables that seem to be the domain of some slightly frightening paramilitary types and drunks. Appealing cafes surround and the neighborhood was lively with a mixture of families and young people – perhaps too lively. One night around 4:00 AM we were awakened by someone buzzing the doorbell! That aside, the apartment is quiet due to its location at the back of the courtyard. There’s a central corridor with bathroom, kitchen and one bedroom on one side. Living/dining room and another bedroom are opposite. On the kitchen side, each room is the same width making for a spacious bathroom and an extremely narrow bedroom. On the other side, the living room is comfortably proportioned but the bedroom is also pretty narrow. Some reviewers found the place dark and damp. This was not our experience. Although it doesn’t have expansive views, the exposures are pleasant and there was decent air circulation. The owner doesn’t occupy the apartment, so while it’s furnished comfortably there’s not much decoration. It also didn’t have much in the way of toilet paper. I fully expect to buy my own when staying in an AirB&B but it would be nice to not have it be the very first thing I do after traveling for sixteen hours because there’s less than a quarter of a roll. The apartment was clean but as others have noted, there were some little signs of inattention. A bucket of mop water was left in the bathroom; there were glasses in the dishwasher – dirty? clean? Who knows? Since the owner isn’t present he’s hired a woman to greet renters and deal with the property. She was efficient but a bit coolish. We appreciated that she was at the apartment when we arrived some thirty minutes earlier than arranged, but she did some little things which were kind of annoying and in my view a bit inhospitable. Some examples: We’d been informed in advance that a second set of keys would require a deposit of €75. Having just gotten money from an ATM, I didn’t have exact change. I asked if 70 would suffice. “80 would be better,” she said. OK. When she showed us around the apartment, she pointed out extra towels but threatened us with an additional charge if we used them. We had an early flight out of Berlin on the day we were to leave and she needed to come to the apartment to retrieve the keys (and return our €80) but told us if she came at 7:00 or earlier there’d be €20 surcharge. I suggested she come the evening before but she rejected that idea. None of this was a big deal and didn’t negatively affect our stay but, coupled with the fact that she didn’t smile, it left a bit of an...
