Once our host gave us the wrong key, had no way of getting us the correct one, and they just wanted to cancel the reservation. This was 9pm and there was curfew due to COVID restrictions, so we were not allowed to go outside the building. I had to beg for about 4 hours to the rude host so they do not cancel the reservation and to call a locksmith. Airbnb's answer was that it was all good because we were able to get in.
