I don't Airbnb much, but the couple of other times I have, it felt much easier and safer.
First, getting the key and checking in was a hassle. I had business meetings throughout the day of my arrival, and expected I'd be able to get into the apartment whenever it worked in a dynamic schedule using a key in a lockbox or picking it up somewhere nearby at my convenience.
Getting the key from Kirill involved a lot of coordination and getting a friend to drive me out of my way and theirs for the convenience of the host and his friends. This was definitely less convenient for us AND for them!
As this was happening, I decided to look more closely at former review and saw the one about the Apple keychain tracking. This is true, although I am quite certain nobody entered the apartment while I was there (and I only went to sleep from 11pm till 5:30am). Either way, it made me feel uncomfortable.
When I did check in, the door was unlocked and the top deadbolt lock on the door was broken and unusable. I was able to lock the door with another lock and a chain, but overall, the whole situation made me feel uneasy.
Finally, while the apartment was clean in general, the bedroom smelled of cigarette smoke. Ugh.
Unfortunately, I would not choose this apartment again. Made me wish I'd paid for a hotel.
