I stayed at The Old Vicarage in Llangurig for 6 nights while walking in the Cambrian Mountains and The Wye Valley. This B&B has only four guest rooms, so I enjoyed an excellent personal service from the owners, Mike and Diane.
The superb breakfast was provided at a time of my choosing. This was most welcome as I wanted an early start on some days. Home cooked evening meals were available, and I made use of this service on two nights.
My double room was large enough to contain a seating area as well as the bed. The bed was very comfortable. One very minor niggle. The en-suite had been created by taking a corner out of the room. The gap between the corner of the bed and the corner of the en-suite was a little tight. the en-suite itself was very good, with an excellent power shower.
On my last night I was allowed to plug in my electric car, giving me a full charge on departure.
