For starters the add said twin beds but they r double. We talked about it and they said that there were more beds that we could use and that we would be alone at the apartment but the surprise was at the check in, without previous heads up, that they were at the apartment too. They are not as cool and flexible as they claim, and if you have some kind of intimacy in the room they would tell you off.
It's true that the communication is quick but not clear. The apartment is clean but very small. They expect us for one of us to sleep in the living room when they were around... So we were forced to sleep in the same bed and then they complained because we got friendly. We (the guests) were just friends before that trip.
