Wrong Check-in information, apartment NOT clean when we arrived (although we arrived much after 16:00), WRONG communication (he promised us we would sleep for free without any doubts because of all the check-in issues, but only refunded us part of the money). I had to go through the mediation center to claim back the money (which I received --> means we were right!!). From the moment it was about the money he turned from a super polite guy into an aggressive behaviour, even threatened me to send someone to my house in order to leave a negative review. Very scary, unpleasant experience, would not recommend anybody to get involved with the host!
