@Mireille312 I'm not really sure what the problem is. It looks like your listing is brand new? Maybe this is your first guest?
You can't dictate guest behavior. As far as "he's" concerned, he rented a room in your house. He doesn't know that you're expecting to interact with him on a regular basis. Too quiet? If you require your guests to be noisy, you should put that in your listing.
I would strongly suggest that you review your listing and make some radical changes. You are asking for trouble by having no house rules or restrictions, and saying things like this:
The space
it's a 100 yrs old house ...2 floor storey and a huge backyard with a 6 feet height fence for privacy... parties are allowed only on Saturday ...!!!Guest access
Front door & basement ... The house is equipped with an ADT alarm for your safety ...!!!Other things to note
During the day, you are free to use anything in the house and to do anything you want, be responsible, no international phone calls on the landline..!!!
You offer a bike and a scooter to guests?? Have you thought about liability? Right now you are poised to have the wrong person book your room and potentially cause you a LOT of problems.
It looks like a hot mess. Your post is a hot mess. What, exactly, are you expecting from your guests?
Oh, and your photos. They really need some work. Everything looks really messy, and it's hard to tell what the rental space is vs. the rest of the house. It looks cluttered and messy and really unappealing.
You should look at some other listings and really clean yours up. Good luck. Kia
