There's a few basic ways to avoid retaliatory reviews.
First, get an insurance policy for STRs. This way, you don't need to confront guests with damage claims. If they burn the house down then the insurance company will go after the guest without you having to confront them.
Otherwise, if they ruin the towels and sheets, or break the glasses or stain the rug, chalk it up to a cost of doing business and move on.
Second, screen your guests. Turn off instant book and require them to ask first. Ask friendly questions. Their answers (or lack of them) can reveal a lot. Prevention is priceless.
Lastly, never give them any sense that you may be unhappy prior to checkout. Just thank them and wish them a pleasant journey home. They'll think they got away with itsnd very likely wrote you a glowing review.
You however, should write the truth in your review of the guest. If you had seen that review, you would have declined them and avoided the entire episode.
I hope that helps. Good luck and happy hosting.
