@Jean-Marc92 Presuming you have a security deposit, it would be best for you to read the specific steps to be taken for making a claim as outlined in the Help Center article. Since contacting the guest is part of the required process, if you feel the guest would be defensive and write a negative review, you should take the reaction into account for the claim process. If you think the guest would react in a way that accepts responsibility, then it might be worth it to submit a claim.
Usually it is a he said/she said situation and the burden of proof is on the host.
