Your location and outdoor features look perfect for a relaxed holiday. In most locations my biggest concern about a house with your size and amenities would be guests throwing out-of-control parties with many unapproved guests. Your listing has no rule against any of this, and I'm sure some people will be considering it, but I don't know how much of a risk it is specifically in your location. Even so, it doesn't make sense for a place this size to be available for bookings as short as 1 night; I strongly recommend a longer minimum length of stay.
In terms of guest count, your sleeping areas seem to accommodate more people than the living space is set up for. If more than 8 people are staying, they will notice things like they can't all enjoy a meal at the same table or sit in the same living room. Not a problem at all if some of the guests are infants, but your listing specifically mentions that major features are not safe for children. That puts the way your home is furnished somewhat at odds with your target clientele.
Personally, I would only go for one double bed per room and filled the space with different features to add luxury appeal (more workspaces, wardrobes, reading lamps, soft rugs). Obviously you're not about to throw out 2 of your beds, but the latter is still possible. And don't offer the living room sofa as a sleeping space. I think a lot of new hosts believe that they can maximize their listing value by offering as much occupancy as they can possibly fit, but a group of 4 to 8 adults tends to have a lot more money to spend on accommodation than a family of 13, and your listing is actually more visible in searches for a group of 8 if the maximum occupancy is 8.
