Your place looks lovely and the photos are good quality and look professional. I would maybe edit them down a bit though as there are a lot. Also, a couple are a bit dark. Personally I think daylight photos are preferable, even in a dining space that you imagine people using more in the evening. Try to take them on a nice bright day and let in as much light as you can.
RE the entire space thing, I think you need to make this information more visible as a lot of guests don't read everything. Perhaps you could specify 'entire top level' or 'entire upper level' of house in your opening description so that guests get from the start that it's not all levels of the house. I think this is a really important point as some people may find it off putting to have someone else there in the building, whilst others might be terrified of dogs.
Another suggestion would to be to always reiterate this point to guests when they request to book (or as soon as they instant book + ask in your pre-booking questions if they have understood this). This gives them a chance to change their minds if they had not noticed/understood that point. Even if they have already booked, they usually have 48 hours to change their minds penalty free. I would certainly make sure guests are crystal clear on this as early as possible to avoid any misunderstandings once they arrive.
You have a lovey listing. Best of luck!
