Place is ok. Host is not very patient in general.
We checked out early in the morning since lots of driving to do. It turns out the door does not lock itself without a key. So that is a catch 22 situation: We can't lock door without key but if we lock it, there is no place drop the key (no mailbox, and nothing mentioned in the rules). We were in a hurry so we made the decision to leave the key on the table and just close the door(unlocked). We were sort of comfortable about it because 1. That is kinda of a airbnb "convention" and 2. there is another gate of the whole building. It was early so we inform the host a bit later at about 10am.
The host freaked out over the phone and whined for minutes...
Yes, it is our fault. We should have wake him up at 6am and ask him about it. But some advice for all airbnb hosts, please use self lock doors or put specific guide in the rules about how to check out to your hearts content. If not, do not whine like a girl afterwards.
