We arrived to the flat and could check in fine: you receive a code that unlocks a box with thw key at the door of the building. Communication was also ok. When you enter there are many stairs (I counted 34) so it is not great if you have to carry a stroller upstairs (this was not in the ad). The flat had been "redecorated" and did not match exactly the description. There were no desks and chairs in the room as advertised and only a high bar and two stools at the kitchen. The main problem for us was the smell: they had obviously just paibted so it was not possible to sleep there and we had to leave, which was more expensive, stressing and time consuming. The first room (we were in appartment B) smelled of paint and something else very strong and was next to the flight of stairs, so not ideal for children if you leave the door open. The second room smelled only of paint. So there might be another issue there with one of the rooms. This is not a flat per se: just two nice big rooms and a bathroom and kitchen but no living room at all. The communication with the hosts was ok and they offered to bring back chairs so we could all sit.
