Llwyn Onn Guest House

Quaint house. Clean spaces. Every morning, the ladies fusses over what they can get you for breakfast. Feels like being at a grandmother's house.

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 .

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.

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.

A lovely B&B in the heart of the national park. Great location to access lots of hiking routes. Very clean room with new modern bathroom. Beautiful view from the windows. Parking spaces available. Very happy with breakfast selection and service. We would stay there again.

This is a fabulous B&B. I would recommend to anyone traveling in the area.

Everything that was said on the comments was true owner couldn’t do more for us, extremely helpful service very good, rooms were good and spacious, with a good knowledge of the area we saw what we went to see. Excellent recommendation.

Visiting Merthyr to visit friends our our way home from a road trip around England, Scotland & Wales. Large comfortable rooms, very friendly staff, great location. 200 year old house, well cared for, modernised and equipped to a very high standard. My Mother had poor mobility and was accommodated very well with a spacious ground floor room. Our room on the first floor was very comfortable too. Full size and very deep bath. Plenty of pillows and towels available, no need to ask for anything. Lovely communal areas if you wanted to sit with others. Breakfast was fantastic, plenty and good selection. Thank you Moira and your team.
