Liked: Staff & service
Disliked: Amenities
Reviewed bearing the price point in mind. Likes: This located very close to the Brecon peaks including Pen Y Fan, so it's an ideal hikers stopover. More than adequate rooms including fridge, hairdryer and ironing board plus good storage and a bath for a soak after your day's walking. Friendly staff. Dislikes: Old building so condensation is an issue (in our room 3 at least). The Internet was down when we arrived, due to a road accident the night before. Admittedly this was not the fault of the B&B but, as neither of us had mobile signal, this made planning our next day impossible. This is pretty trivial for most people but, if the proprietor had informed us we could have chosen to stay elsewhere and avoid not having one of the amenities that we paid for. Business travellers rely on hotel Internet access, so this could have been critical.

you will not want to stay anywhere else.
this was our 4th visit to this B&B, sadly it was fully booked earlier in the year and we stayed at a Travelodge,( which we would rather not do again.) this B&B is always spotlessly clean ,staff are beyond lovely, we stay here to take the strain of family having to put us up when visiting .

An amazing top grade guest house.
The guest house is the best I have ever stayed in as it is of such a high standard fir the money it us amazing. The breakfast was delicious with such a great selection. The owner and staff are so lovely and can't do enough for you. If you are looking for a guest house in the Brecon Beacons then look no further.

wonderful Brecon Beacons stay
Great stay - property was easy to find and very private, room was very comfortable and breakfast cooked to order as well as cold buffet was generous and delicious. We stayed here before riding the Brecon Beacons Railway and enjoyed a quiet evening and warm hospitality of our hostess.

Easy check in—keys and instructions left for me, so since I arrived before the office opened, I could let myself in and settle in. The location, on a loop road just off the main road, is quiet and safe from traffic, and affords lovely views toward the Llwyn On reservoir, a short walk away, and along the ridge behind the house. Easy access to trails, and by car or bus to places further away (Brecon, notably). There's a bus stop right at the road. Classic and generous breakfast options (incl. vegan). Very comfy bed, nice bathroom, and everything one needs en suite for tea or coffee, and biscuits. Moyra and the staff were delightful, ready to help as needed.
