The entrance system to the apartment is with an app, both for the exterior door and the apartment door, if you don't have a battery in your mobile you can't enter. Once you cross the outer door you need a key to move the elevator (up or down), no matter if there are 4 or 6, the owner only gives you one key. When I raised this problem the answer was, use the stairs, after insisting and being ignored we tried the stairs, but oops, without a special key you can't get through the door of the stairs.... I'm not going to blame them for falling the elevator and have to be rescued (without injuries and very quickly) but the lack of response as a host is disappointing. Another detail, do not expect to store clothes on closet shelves, they have large and comfortable closets, but without a single shelf... The only good thing? The flat is located near a convention center where we had to work for a week. Removing the logistical discomfort, the floor is correct.
