Hi Janet,
I still can't tag people here.
I also rent a room in my home. I have only had one guest want the whole space, but they were aware that we live here, and sent an enquiry asking if they could just have the entire space anyway. I was uninterested in moving out, as you can imagine.
Anyway, I think I avoid confusion by being clear that we live in the home in several places.
First of all, the title of my listing is Private Room in the "village inside the city", just to reiterate it's not the whole house.
I've captioned the rooms that will be shared as such in the photos.
Under the section called 'the space' I lead with mentioning that the guest can enjoy a private room in our home.
Under the section 'Guest Acess' I reiterate which spaces we share, and how often we use them in the 'Guest Interaction' section.
My house rules also mention we're in the home, and that we get up to go to work on weekdays, but will be quiet in the mornings and expect the same from guests if they come home late.
Finally, I always begin the first introduction with the phrase "Fred and I look forward to welcoming you to our home"
It might be a bit of overkill, but we all know how often people need to see something before it sinks in. You might want to consider mentioning a few more times which spaces in your home you can expect to be seen in.
Good luck,
Mel
