1) It's a hotel passing off as an Airbnb, so the room you see in pictures is not necessarily what you're getting, just like when you book a room at a hotel.
2) You have to have your own soap, shampoo, and towels. It says it somewhere on the listing, but you usually don't expect that or read the whole listing anyway, and at least the soap is just the most basic thing to expect at a hotel/Airbnb.
3) The AC is not that powerful and might not get to the bedroom. Oh and it just stopped working, with no explanation or anything, for the last day we were there.
