Hello @Elad4,
I know this post is long due but still, to avoid this from happening again make sure you contact the guests the night before to see if they need "further assistance" before checking out tomorrow. Maybe they need a taxi being set up for them or something, it's always a great excuse to contact them, remind them of the check-out time and date.
It is vitally important that you NEVER touch the guests' belongings, even if you feel you're in a rush because it's past the check-out time and you have to clean and another guest is coming. This can get you into a lot of trouble, especially if something's missing (they might even say they had jewelry with them just to take advantage of the situation).
For things like this always use the Airbnb chat and request Airbnb to contact the guest themselves, so you can have evidence that you tried to reach out to the guest in case Airbnb needs to place your new guests somewhere else.
Regards
