tl;dr: We decided to leave this property and asked for a refund because clearly nobody cleaned it after the previous guest left, and the unit was disgusting. Host was non-responsive after being informed of the condition of their property.
Full facts: After a delayed flight, my girlfriend and I finally checked into this unit at around midnight. We were first shocked at the state of the bedroom: 1) Clearly nobody tried to make the bed since the sheet and pillows were a mess, with a used blanket on the top as well. We then found human hair and some cotton balls on the sheet. 2) Used towels were placed randomly on the drawer.
It turned out the living area was no better: empty beer cans were left on the counter, and there was some packaging of cold pills left on the coffee table (which means potential COVID exposure for us since the place was not cleaned after last use). The garbage bin was not cleared either. Finally, in the bathroom there is one used bath towel hanging. We could not find any other towels so it was impossible to take a shower there anyway.
Without even opening any of our suitcases, we decided to call Airbnb and asked for a refund. The call took a while, and it was almost 2am when we left the unit and had to find a hotel room in this city that didn't cost like a grand a night. We also contacted the host and sent them all our evidence immediately after the call with Airbnb, but it's been radio silence from the host. Not a word. Airbnb approved our refund request the next day after reviewing our evidence.
