"Would stay here again"

9.0

Clean and comfortable room, slept well. Attentive and welcoming staff. Lovely Welsh breakfast.

The shower temperature was too low for us even after letting it run a bit as suggested and would prefer a a shower head on a hose . Feel that the shower could be updated

We had a lovely stay, the place felt like staying with family the owner Moyra and her team were all so nice and charming. The room was very spacious and comfortable, there was good parking space in the yard and the breakfast was wonderful, cooked well with very good ingredients (my partner kept complimenting the quality of the sausages). Very short drive to go explore the Brecon Beacons, and other beautiful places in the area. Thanks Moyra and the team, all the best!
