I was expecting a non-smoke room when booking, but received a room that had been heavily smoked in; We kept the ventilation on for the whole night, but can still easily smell smoke from the wallpaper and mattress, which gave us a headache. We had to cut the stay short and left the room the next day because of that.
The room is reasonably clean on most surfaces, but we found the bedsheet dirty (looks like shoes stepped on it). The host was quick to respond and sent the onsite cleaning lady. She told me it is clean (the footprints on the sheet are due to "bleach", which I find it so hard to believe how bleach can put darker color on a white sheet); anyway she brought up a new sheet, which was clean this time.
Other that the huge problem with smoke smell, this place is fine. The host's communication is polite and quick, but not always resolving the problem. Getting a full refund because of the smoke problem is talking a lot more back and forth than I expected.
