I just go for it, honestly, and ask for whatever I think they owe. If you don't make a claim quickly, such as right after the guest has checked out with corresponding evidence, you are unlikely to win it. If the review is in retribution to you asking for reasonable recovery to your items or damage, you can sometimes get it removed since it does not reflect the truth. I think the claim should be filed with Airbnb and they will look into it. It is what it is, but business is a business and it's not worth it to suffer for damages done by the guests.
