We stayed in the ground-floor apartment, so we can’t comment on the others. The cleanliness was good, both in the rooms and the linens, which were very clean. However, the photos don’t reflect the actual space: the entrance has only one small window overlooking a rather dim alley (not as shown in the pictures), and the rest of the apartment feels extremely claustrophobic. It’s almost like being in a cave—no natural light, no windows or openings, and a very humid atmosphere, even though there was no unpleasant smell.
Luckily, we only stayed for one night, as I wouldn’t recommend it for longer stays.
On top of that, although we had booked for three people, only two sets of linens were provided on arrival. When we asked for support, we were told to collect them directly from the laundry. We did, but it was not a pleasant experience.
