We arrived late at night to discover the keys that we were supposed to collect were not there. When we called the host to work out what went wrong, she was rude and implied we had not followed the lengthy instructions she had sent us. Eventually it became clear that there was actually someone else in the apartment we rented; he too was confused, and it turns out was supposed to be in the apartment downstairs which is also rented on airbnb by the same host. The confusion isn't itself a huge issue (although it is caused by the fact that this place is run as a business where the host doesn't ever meet the guests, just sends an endless stream of messages with instructions). But the rudeness when we called to find out what was wrong, totally disrespectful. Otherwise, the apartment was OK and clean, though if 5 people actually stayed here it would be like an overcrowded student dorm.
