This is exactly the sort of experience I seek when visiting the UK. It's an "only in England" experience. From the moment I arrived until the moment I left I was absolutely enraptured. The proprietors ran out to greet me to show me a better, safer place to park my motorcycle. They checked me in, showed me to my room, and have me the rundown on local dining options. My room was quiet and comfortable. The bathroom had an ENORMOUS tub. Their gardens, which are clearly a labor of love, are astounding! Another plus for gearheads like me is that they are enthusiasts of unusual sports cars, including building kit cars (e.g., Caterham 7), and serve in a leadership role for a local car club, and also serve as a local historian for their area of the Welsh Marches. Such energy! More flexible around what is included in a full English breakfast than I've ever experienced.
Downsides? Well, the stairs are steep. And, if your preference is for the vanilla experience of a Holiday Inn, this probably isn't for you. If on the other hand, you travel to meet people and learn new things, especially if you have any appreciation for any of what I've described, this might be just the experience you're seeking. I, for one, plan to come back.
