This was a really awful and weird experience. The hosts were unwelcoming and inappropriately contacted us all throughout the stay to remind us of the extensive (and unfair) rules they had about the house. They came to find us after check in at a bar with our friends to ask for more money, then later accused us of having those people to stay in the house, which was not the case. I have used Airbnb extensively and have never had a problem, I've always had great experiences and responses. These people made us feel like we were doing something wrong. I understand that many groups come to Amsterdam to party but we used the house respectfully, and honestly were mostly out and about. They did not communicate regarding check out and then let themselves into the house before check out time while we were all still asleep. There were notes on everything in the house outlining what could and could not be touched or used. The courtyard advertised, we were not allowed to use at all.
Do not stay here!
