We have rented holiday homes all over the world for years now, both through agencies and direct with the owners, and like to think that we leave the properties we rent at least in the state we found them, if not even cleaner and tidier.
There are good and bad potential tenants out there, and all you can do is remove all your valuables, and have insurance in place before handing over the keys.
Personally, I wouldn't list the property with air bob as they seem to limit the contact with the renter beforehand allowing you to check them out.
