@Charles444 There are many discussions about how to provide incentive for guests to tidy up and there are several great ideas, but the least effective as @Letti0 has posted is to financially "reward" the tidy guest. The best you can do is to vet potential guests along the lines of looking for reviews that reflect the guest was tidy and respectful of the listing. Additionally, clear and concise expectations about cleanliness in a written form is helpful.
That being said, if you fully expect to have repeat guests, you could provide a refund as a thank you and the guest will have another reason to re-book.
