So this scene just went on in your home and you didn’t speak to them about it, just acted like it was normal?
Successful homesharing requires hosts not being afraid to simply speak to their guests if something is bothering them about the guests’ behavior, whether it’s them leaving a mess in a shared bathroom or kitchen, coming home late and noisily and thereby waking up their housemates,etc.
As a homeshare host myself, this would have been my communication with Lesley, from square one:
“Lesley, I’m confused by what is going on here. You may not have realized this, but the person who books has to be the person who stays, and the people who are using the accommodation have to be accounted for on the booking. You booked this room for yourself, not for Marvin, and you didn’t give any indication that the three of you were planning to spend time together here. This is my home- I provide accommodation for paying guests, it’s not a meeting place for families, and I feel disrespected in having assumptions made that you didn’t need to inform me of your intentions. I’m sure you didn’t mean to be disrespectful, but we now need to figure out how to move forward with this.”
As to how to handle a situation like this beyond the conveying of the info that what they are doing isn’t okay, different hosts might handle it differently. Some might not mind these folks spending some time together, as long as it was just brief visits, not them all using your hot water, toilet paper, towels, etc, as long as that intention was disclosed when the guest asked to book and approved, some might adjust the price on the booking to accommodate the added usage, some hosts might not want more than the person to booked to enter the home.
When I found out after she had arrived that one of my guests was in town to see her son and grandkids, was having to visit them at the mom’s place, where the kids were living, and that she and the mom didn’t get along, I told her she was welcome to have the kids over sometimes if she wanted, as I live in the countryside and there would be plenty of nice things for the kids and her to do outside. She didn’t take me up on it, but I offered because she seemed really distressed with the situation at the mom’s place (said it was really dirty and chaotic).
However, when a single female guest brought a male friend back one night without asking me, I put a stop to that right away.
