Airbnb typically doesn't "resolve" issues of guest violations of house rules or trashing of the premises. That's >your< problem.
If you're lucky, and you can prove actual damage (e.g., something visibly broken as a result of guest behaviour or negligence) then they sometimes will offer some compensation, but usually only if the guest admits it and agrees to pay, and only if the claim is fully completed (with all evidence, repair receipts, etc) before the next guest checks in (which could be hours).
The other flaw in that system is that if you make a claim, it's almost inevitable that the guest will write a "retaliatory review", which affects your ratings, and cannot be removed, even if it's completely fabricated nonsense. And regardless of what people say, ratings are important.
So, we've resolved to a strategy of "prevention". We vet guests extensively when they have no profile, no reviews, no history, and especially when their inquiries seem a bit "off". Sometimes we'll demand a (real) security deposit. This usually scares off the riskiest guests, although there are rare occasions when they make it through the gauntlet. Then we just have to chalk it up to another "educational" experience and move on.
Otherwise, we never ask or expect Airbnb to "resolve" anything. It's usually just a frustrating exercise in futility. I have more important things to worry about.
