@Kristy28 I would recommend deciding on a reasonable additional cleaning fee, replacement costs, etc and reaching out directly to the guest to have them reimburse you via a payment application. I have never used the resolution center because I think it's really only useful for extreme cases.
I have found that every guest that overstepped the cleanliness rules was willing to pay additional fee when I asked them to. The key is remaining calm and remembering this is a business transaction.
Something like,
"Dear guest, I appreciate your stay and enjoyed communicating with you but I am disappointed in the way the house was left and need to ask you for a reasonable reimbursement for the additional costs I have incurred. Garbage was left around the house, dishware was not cleaned, vomit was evident in one of the rooms, and the upholstered chair in the living room is damaged from sneaker stain. I respectfully request you reimburse me the $100 in additional cleaning costs and fees I will incur as a result. I trust you will find this a reasonable request. You can transfer the funds to my online payment application at xxxxxx."
But you need to do it immediately.
