I am looking for advice on making it very clear to guests that they are booking a private room rental. In the last month, I have had 3 reservations that have booked and cancelled because of them (one of them was a month-long stay). To date, I have always approved a full refund (even though I have a strict cancellation policy) because the mistake is corrected on the same day, and I don't want people in my house that feel financially forced to be there.
My listing is classified as a private room rental (so they can filter based on this, and it says it on the reservation page). I also mention this fact TWICE within the listing description, though I know guests frequently don't read the entire description. I believe it's also listed under "Things to keep in mind" during the booking process. To me, I think this makes it pretty obvious, but I still frequently get guests that did not realize they were booking a private room and not the entire house. I have literally thought of uploading an interior layout diagram of the house with color-coded legend of guest private space, common space, and off-limits/owner areas, but then I have to assume guests will look at that photo, and if I do too much, other potential guests may be deterred from my listing.
To head this off, I send them a welcome message over AirBnB and a welcome email that both mention the fact that it's a private room rental (this is where guests always catch their error and contact me immediately). I am not one to simply take someone's money because of a mistake, and like I said earlier: I put a lot of time and care into my house and don't want people that feel forced to be there.
Here is a link to the listing if it's helpful to see it (though I just added the wording "Private Rooms" to the title today in hopes that might help):
