Hello @Karen480,
If you take lots of photos of the couch damage, and get the claim in within 24 (48?) hours, then you can try to have the guest pay for the damage through the resolution center. This is tricky, though, because it depends on the guest agreeing that they did the damage (and are willing to pay), so you will need good proof. If you do this, I would only recommend that you try having them pay for the couch. It would seem a bit nit picky to have them pay for the pillow, even though I agree, that is totally annoying.
Definitely keep all communication on the Airbnb message system so the company can see the thread. And if the guest agrees that they did the damage on the message, it may help.
