Booked one three times. Three times booking got canceled on the arrival day. Fuck Airbnb.

You need to call ahead with hotels if you're going to be late to check in, but otherwise, they're good.

Edit: dont know why I'm being downvoted. Ever reserve a hotel room for a big convention and show up at 10pm of the check in date? They will give it to someone else because they're betting on you being a no show. You gotta call them if you're doing a late check in.
