Check-in is self-check-in, so the host leaves the keys outside the apartment. However, it is impossible to find where they are! I called him, he wouldn't pick up. I had to ask a neighbor who then show me where the key were stored, saying that everyone struggles with that.
House smells of fried oil, as it's above two takeaway shops.
Bed sheets were dirty.
Electricity was off (we had to switch it on) and radiators did not work. One window in a bedroom wouldn't close properly, it was freezing.
Overall: horrible experience
