@Rhonda268 While you list it as a private room, it seems most guests these days do not bother to read even the most obvious things. They look at the pictures and the price. You have to assume they have the reading skills and attention span of a kindergartener.
Your photo gallery is one of the main problems. While a pool is definitely an attraction, do not use that as your cover photo. Use a bedroom photo and order your photo gallery to show the guest bedrooms and bathrooms first, and the common areas after. You have far too many photos of the living room and kitchen. It makes it seem like the guest has this whole huge house to themselves. More photos is not necessarily better.
The first line of your listing description should be "Please note: This is an owner-occupied listing. Your 3 bedrooms and your bathrooms are private. The living areas and kitchen are common spaces shared with the host, whose bedroom is upstairs.
Then go on to describe the space and the amenities.
Hopefully those changes will help, and I'm sure some other hosts here will have more suggestions.
