Overall a very bad experience. Fortunately it was only for 2 nights.
The apartment was advertised to have checkin at 13.00 the host insisted that the check in is at 15.00. The host later changed the listing but the email I received from airbnb upon reservation still says 13.00.
We finally checked into the apartment at 15.00 after waiting for 30min on the road. The apartment was not ready, the cleaning lady just got into the apartment with us so we had to leave and let her do her job.
The apartment had a persistent (bad) smell. It was rather dirty, with stains on the floor and the walls.
There were bugs in the coffee machine and in the cupboard. The towels had brown stains and were wet. I asked the host to bring fresh towels he said ok but never did. The bed sheets had (cigarette) burns. I have photos for all of these.
