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.
