Everything started with confusing check-in instructions. The place hadn't a "mechanical" key, so one would be doomed to suffer every single time.
Next thing we noticed is dirty couch – hairs, fur, stains, everything. We thought about vacuuming, but the vacuum was full of previous guests' dust. And finally, a lot of dust on chairs and lamps.
But all that didn't matter, because within 15 min in the apartment we located two video cameras, in the living room and the bedroom, facing the bed. The host company tried to convince us that, first, those weren't cameras (although, they had camera eyes and letters "HD VIDEO" and "720 P"), then, that they are not filming anything. The latter might've been even truth, but we obviously didn't want to check it in our own skin.
Of course, we left the apartment before night. AirBnB were helpful and understanding: They paid for three nights in a substitute hotel, while we were looking for something else, and fully reimbursed this booking.
Stay away.
