@Marguerite65 I don't know what you can do at this point except check local pawn shops for your jewelry and other stolen goods. I once had an $8500 ring stolen by a cleaning woman (nothing to do with Airbnb) and faced a similar situation where I knew what had happened but had no evidence and a very uncooperative cleaning franchise manager who did not want to admit his employee was at fault for fear of losing his business reputation. So lessons I learned and other suggestions are:
1. get a safe and keep it well hidden.
2. rent a safety deposit box at a bank for any valuables you don't use a lot.
3. check your guests IDs at check in
4. Put locks on any doors where valuables may be kept.
5. Get a dog who will alert you if the guest is going into parts of the house that they shouldn't
6. Get more coverage on your home owners insurance and appraisals for anything of value. Keeping receipts works too, but things like electronics and purses don't generally get you 100% reimbursement unless they are brand new.
