Be incredibly careful about booking unless your entire family or group can be quiet as a church mouse at all hours of every day. The neighbors absolutely hate that this apartment gets rented to travelers (and they have posted signs in the elevator, in the hallway, on their door (that one in particular begins, "Dear 4th floor travelers, this is a quiet building and we are totally exhausted of the situation...[and so on]"), etc.) and menacingly threaten to call the police at the slightest hint of peoples' presence. The wifi is also very slow and does not reach past the kitchen reliably, so if you plan to do work from this - definitely very beautiful and spacious - apartment, reconsider.
