Beware of Moderate Cancellation Policy, Negative Reviews

My family of four plus two grandparents booked a whole house in Phuket, Thailand with a moderate cancellation policy, allowing for cancellation during the stay. In the master bedroom, the en-suite bathroom smelled of poor toilet drainage, and the house was generally filthy despite the advertised housekeeper. After a few nights we decided to cancel and book ourselves into a hotel. We would have acted sooner but were very jet lagged after a 24-hour flight, We gave the host a heads up and followed the moderate cancellation policy (allowing for a 50% refund for unused days).

The host was very angry and wrote a negative review saying we were the worst experience he ever had. We left the house in a cleaner state than when we had arrived with no breakages. We were highly courteous throughout the stay. After going back and forth with the case manager Airbnb decided that the review was within guidelines. I am writing to warn future guests to document everything through email and photos and if you make a complaint do it within 24 hours even if there is a moderate cancellation policy.
