This Airbnb host listed a room with a private bathroom. We left the room locked on our second day. The host or his child used the bathroom and bed while we were out of the house sometime that evening. Photos show a rumpled bed and pillows displaced; a wet towel was hanging up, and someone else’s toothpaste and toothbrush were on the window sill. The house was full of smoke although the listing clearly indicated “no smoking.” No one else was on the premises during this time. The host was very agitated and communicated to us extremely personal circumstances including an incident with the police earlier that evening. This made us feel unwelcome and unsafe. We left immediately. The host’s behavior as the evening progressed was truly bizarre.
So your host violated the rules. You are entitled to your money back.
