1. It was said that there would be two double bedrooms, but there was only one. In the second room, there were two single beds. The owner didn’t warn about it.
2. It was very cold in the flat.
3. There was an unpleasant smell in the kitchen.
4. And the last thing that I found strange: the owner took photos of all our passports. I've never encountered this before when renting through airbnb.
