Host hadn’t cleaned the flat since previous guest who incidentally was a total pig: I arrived to a pile of empty medicine packs on the table and half-eaten KFC left out on the desk.
I booked last minute and was automatically approved for contactless check-in, so I understand how the host hadn’t planned to rent out the flat that evening, but in that case please list it was “unavailable” to avoid a nasty surprise.
Host was very apologetic and refunded rapidly.
