If some damage is done by guest you have to take a photo, receipts for the repair or the original purchase or for the new item or the link to the webshop where you can buy the replacement.
Then you submit the damage claim within 15 days or before your next guest arrives.
Then your guest has 72 hours to decline or accept to pay. If he denies or ignores you, you can involve Airbnb to mediate.
But, if you don't have any pictures and you don't have a receipt for the repair then I am afraid you don't have a chance.
Yes, of course, we had some damage done by a guest, if it was a minor thing like the vase or a plate, sheet, towel or most recently the kitchen cabinet door knob then we don't charge the guest. But for broken bed, punched door or broken window we do. Some guests paid, some ignored us so we had to involve Airbnb. Of course, nobody paid for our time, stress and our work.
