@Linda3345 Your listing is lovely. I agree with the suggestion to make it really clear that you live in the same house, in a separate basement suite, and that the guests have the main part of the house, with private entrance.
Put this in a separate paragraph, so it is noticed. You can spin it as a positive- "We live in the basement suite if this house, so we are always available to answer any questions you may have, but of course we respect our guests' privacy."
This accomplishes two things- it wards off guests who show up, assuming they have the entire property to themselves, as well as guests who have intent to throw a party, or sneak in extra guests or pets.
Photos- take better photos of the bedrooms that don't cut off right at the top of the bed frame. Take at least 2 photos of each bedroom, from different angles, so guests can see if there is a closet, desk, whatever is there. And more photos of the kitchen from different angles, as well, not just the sink area.
