@Vince1757 you've actually done a really good job for a newbie! Really- very thorough with the details, and the accommodations look really nice!
The only thing that I would improve upon is making it clear that there are two guest rooms available, and that another guest might be staying at the same time. I think you touched on that in the photo captions, but people DO NOT READ, and I'd hate for you to have a guest come stay, and then be surprised that another guest is in the next room as well as sharing the bathroom.
I think it would benefit you to be VERY CLEAR about this in your written description of the space.
Also, your price seems really low, but I don't know your area. Just keep in mind that low prices attract bottom feeders, and that creates all sorts of other problems.
Good luck! Kia
