This place used to be a hotel, and it is actually run like a hotel, lacking all the charm of a private apartment and the corresponding privacy. I would have liked to know that beforehand. The description is misguiding.
Additionally, I had a security issue. Drunken or drugged neighbors (One floor has like twenty rooms) had a fight, one guy was testing to break the door, shouting for 15 minutes. The host didn't do anything and even instructed the "security" and ground level not to do anything. They didn't call the police, presumably to protect their reputation. At the expense of my security was my impression.
I was unlucky with this event but the key is: I was profoundly irritated how this was handled by The host. The host even refused to discuss this issue in person.
