You're place is so inviting. I want to go there right now!
You know how to show "lifestyle" in many of your pictures, Especially your first pic - very nice.
My suggestions is your get rid of some of the darker pictures and complicated pictures.
Your first pic of bedroom is great, the dark pic of your bedroom is not inviting.
Get rid of the toilet picture - It presents as cluttered and complicated. We don't need to see it, we believe you have a toilet.
The shower picture is so-so. The sink pic is great - simple and bright.
While a nice feature of your setting, the hallway to your separate room is cluttered with a bench.
Your intentions are good. You are proud that you have a shower and you clearly want to show that the room is far away from the main house. But you need to get more clever presenting these in photos. Simplify and exentuate what you want.
Get a professional or get other people's ideas of how to better present.
Good luck
