I have the impression that a couple of years ago (perhaps around 2020), the owner made a huge investment in the rooms, but since then, no maintenance has been carried out. In my studio, a lot of things were broken and/or not functioning properly: 1) the glass box in the wash was not closing properly (making the water spill out to the bathroom floor); 2) one handle in the box was broken; 3) hangers in the bathroom were loose; 4) the lid for the batteries in the remote control was sloppily glued with a sticky black tape; 5) the mechanism that should allow the TV to go around the living room and bedroom was loose and could not stand still in any of the rooms.
It was clear that all of these issues were not new - most of them were clearly old, but they were never fixed. I reported the issues and they offered to send someone to take a look, but when on a vacation (AND WHEN YOU CHOOSE A HIGHLY RATED PROPERTY), you expect the room to be neat and functional and not to make your vacation around a day/time that the “handyman" can come over to fix problems that never should be there in the first place. The high rating seems to derive from the "golden era" of this property, which seems to be sloppily managed nowadays, unfortunately.
However, the location is very good and the neighbourhood has a lot of restaurants and stores, very close to the metro station as well.
