Long story short: Me and my girlfriend arrived to a place where the host was very nice for the first few days, then started with herratic behavior, blaming us for "messiness" to the point that no mattet how clean or orderly we were, he once scolded us pretty bad for not scrubbing a pot we used to boil water for tea! He even scolded us for past things, we also saw him scolding other guests but he seemed to develop a fixation for my girlfriend. Things were pretty bad and we thought about cancelling and getting a refund but we didn't know if we could.
In the end, he kicked us out for boiling an egg with one of the burners of the electric stove that was bigger than the smaller one because the smaller one was dirty.
But things got almost out of control and he could have gotten violent and assaulted us.
Airbnb refunded the rest of our stay and has been supportative. I have used Airbnb about 10 times and this is the first time this happens, it is likely that this could happen again, so what should we do next time if we start feeling uncomfortable with the host?
