Perfect location for the Brecons. Easy to find.

The heating in our room wasn’t on when we arrived but that was easily sorted. The water in the shower was very hot and for my wife only just bearable despite being on the coolest setting!

Like the breakfast, the location and the people running the bnb were delightful!

There's not much to not like, has browns with the breakfast would be nice, but that wouldn't be very welsh.

Great location next to the reservoir, good sized rooms, good breakfast, accommodating hosts

Beds were uncomfortable and bedding felt very synthetic, room got too hot despite cool weather and the water in the shower was only boiling hot, room could have been cleaner too
