@Oxana229 In the future, if you are going to book places where you are sharing the home with other guests, before you book, you should make sure that the private rooms have locks on the outside of the door so no one can enter your room except the cleaner or the host. That way, if anything goes missing, the possibilities of who might have done that is greatly reduced.
If you are only sharing a home with the host, it would be pointless to have a lock on the outside of your door, unless it was an exterior door, as the host would always have a key anyway in case of emergency. And a host wouldn't be able to stay in business if they stole from their guests, so that's an unlikely scenario.
