@Mariam160 It seems that you had the idea that Airbnb was some easy way to make money while you are away, but it isn't at all like that. Not realizing that you need a co-host or having any concept of what issues could arise in your abscence is a recipe for disaster.
No, you can't leave your heirloom vases around- you could come back to find them all broken or stolen. Your liquor cabinet will be decimated. The guests could invite 50 people over for a party and trash your place, upset the neighbors, and lead to police involvement.
You need a co-host who can: attend to orienting the guests as to how everythg works, check that the people who arrive are actually the people who booked and that they reserved for the correct number of guests, who can attend to appliances going on the blink, plumbng or electrical issues, etc, who can keep an eye on the place to make sure nothing bad is going on there. And who won't be scared to make the guests aware if they are not complying with house rules, if they have more people there than they booked for, and to be able to refuse entry to the extras or make sure they leave.
I would strongly suggest that until you have some hosting experience, that you do not rent out your entire personal home while you are away. I have read posts on this forum from hosts who did exactly that and burst into tears when they came back and saw the state the so-called "guests" had left it in.
