Disappointed. In short: dirty; mattress springs broke (sharp edges tore the cloth); ants; the parquet sticks to feet and falls out from floor in one of rooms.
The person responsible for check-in agreed that it was not clean so we arranged to clean it on next day, then they postponed it for 1 day, and then postponed for 2 more days. Eventually, the cleaning team came, did almost nothing (they were literally only 10 minutes inside), and left. I took photos and videos as proof. Sent this to the Airbnb to demand refund. First time in my experience.
We had great time in Porto though =] (outside)
