@Melinda382 What the other responder has failed to mention, is that Aircover claims are extremely difficult and rarely pay out. It's not a protection program, and no host should feel any peace of mind about it.
There are horror stories in this CC about hosts who have done everything right, and jumped through every hoop, to no avail.
AirBnB asks for the same information over and over, a different agent handles the claim each and every time you make contact, and then they deny the claim, telling you you haven't submitted the proper paperwork or a similar story.
Then they deny the claim, or pay out cents on the dollar.
The information in the other response is from someone living in a fantasy land. Just search the community center and you'll know the truth.
I'm sorry your guest destroyed the door, and good luck with whatever you decide to do. Kia
