The flat is clean and spacious. The kitchen and bathroom are well equipped.
However, there are a couple of inaccuracies in the advertisement. Arrival is not autonomous, you depend on the host's sister to receive the keys. You have to agree on a check-in time. There is also no keypad entry, unless you consider the garage access lock, but not the main entrance doors or the flat door.
The entrance is not independent, it is accessed by the same staircase as the family. The whole staircase is full of personal belongings, shoes, etc. The staircase is not as pleasant as the flat.
In the flat there are several wardrobes. However, not all of them are available for use. One is locked and marked as private. In another one we found other people's clothes and in the remaining one there were shelves, so we could not hang our clothes in any of them.
The beds are not comfortable, the mattresses are deformes in the middle. We did not rest well.
My wife and I are over 50 and have some world travel. We don't think we look like "young party people", so we don't understand the need for the repeated instructions to keep the noise down. I understand that if we had been noisy guests, they could have let us know, but it was completely unnecessary "a priori".
We have been using AirBnB and other platforms for years. So far we have been un thriller same wavelenght as the hosts. We are very careful with the houses and aim to be respectful of the people. This is shown by the comments on our profile. However, on this occasion we felt more like a nuisance than welcome guests. We were reminded that it was their home (which is perfectly obvious), although a good host should make you feel at home. Also, it was the first time that a host has made an inspection of the flat just before leaving. We had never felt so much mistrust.
