I mostly love it, OP. Somerset, WIltshire, Dorset, these near West Country counties appeal especially to me and the exterior of the house and its garden setting are pretty wonderful. It's a curious mix of a house as you'd expect for one with origins in the 14thC; obviously there was a lot of work done in the 19thC and 20thC, and likely earlier, modernizing the ceilings about which R2 is mad (early 19thC or late 18thC from the looks of it.) With a house that old and with layers of alterations over centuries it's often best to embrace what one has rather than fight it too much trying to make everything of one period.
It's a really lovely and comfortable house that's flexible to using the rooms for various purposes, it has the one quite large room on the first floor with the grand windows to lend variety to what are otherwise relatively small rooms. I would certainly be tempted to spend the great majority of time in this big space with its many separate areas, window seats, and other features.
Despite the impressive exterior, it's not a huge house inside, just 3400 square feet – not small, obviously, but the exterior does suggest something altogether bigger in size. It's manageable inside and outside at 9/10 of an acre. The two separate buildings could function as a rental and a small guest house, or some combination: small enough that you could let them them sit there little used, or put them into service, even as income properties, without making a full-time job of it and while maintaining some privacy in the process.
The rooms are all rather pleasant or better. The current furnishings and fitted carpets and some finishes are something of a let down, but of course the furnishings leave with the owners. It's a house that needs a certain amount of period furniture to tie things together, but you could certainly mix in modern furniture and art. The kitchen is rather nice, maybe the modern cabinetry is a bit dated and I would paint it, but it's not a house where there needs a massive plan to furnish it or to change the finishes to taste.
The house is just outside the village of Freshford, with some pubs and everyday needs, Bath is just 20 minutes by car (and from there 80 minutes to central London by train.)
I'm not sure that it's the house I would pick at that price as there are other early houses that suit my taste more and cost less, but it's a great house.
