Our room had mouldy walls and pillows. The room smelled terrible and was extremely moist. At arrival it smelled strongly like vinegar. Later on when the vinegar smell got less the mouldy smell got through. We mentioned the problem and got offered an alternative room but had to wait for it another night. The mould was so strong it broke out of the walls, the wallpaper was soft and was falling apart at some spots. We decided to report it to Airbnb and got a refund and checked out early. Only one night caused strong allergy symptoms with my partner and swallen lymph nodes for me. Maybe the rooms with windows don’t have that problem but it certainly is an ongoing problem already at the house. Alejandro was really nice and shortly after we reported the issue to him cleaning stuff bursted into our room and started rubbing the walls with vinegar. I’m quite confused about the whole experience and hope that the problem will be fixed professionally soon for coming guests.
