Horrible experience! We got locked out of our stay.
Tip: Don't leave the key in the door, you won't be able to unlock it from the outside.
This isn't documented anywhere and the host pretended they told us when all five people in our party don't remember him saying anything about the keys.
Also: What kind of door would lock yourself out? This would never happen at a hotel. I recommend booking a hotel and avoiding the risk of you not getting your stuff back and getting charged a locksmith fee.
I've stayed at 20+ Airbnb's and this one's one of the worst. Stay away!
