Checked in much like in an hotel, very quick presentation of the apartment, keys handing and that's it. The description is realistic. One thing you don't see on the pictures is that most of the rooms are not straigt. The kitchen in particular is really on a slope.
Good place for young people to stay in for a few days ( we were there 6 days) if you want to discover Lisbon. Comfort is minimum but the location is great.
