TERRIBLE EXPERIENCE. BEWARE.
The host sent vague threats and called me names at 2.30am on a Sunday after a cleanliness complaint (smelly mould infestation in the bathroom/ potential health hazard) that I'd sent first to him and then to Airbnb, whose support rep appreciated my concern and offered an immediate 1/3 refund.
In the end I cut our stay short because we were afraid of him. I tried to call him three times to arrange earlier checkout but he didn't respond to phone calls nor messages on Airbnb. I reported him to the Trust and Safety team at Airbnb and hope he won't be able to host for long. Definitely one of the worst travelling experiences in my life and I've been using Airbnb since 2014.
Here are some bits of the message he has sent to me (direct quotes):
"Be sure i'm not gonna let it go that way with your complain to airbnb. I mean, this was 50€/night. Go sue those wealthy people taking advantage, not someone like me. Bastard.
You're the mould.
I would appreciate you put a zero on your pleasant stay in my flat. You can even steal a few records and books if you want, i wouldn't be surprised. Airbnb is the wreck of civilization and culture anyways.
Make sure the poor get poorer cause they can't manage to cure a little mould in their bathroom."
Stay away from this host.
