Six adults, a baby and a very well behaved dog stayed here in September for two nights and we've all said that we would happily stay here again. Finding the accommodation was easy, thanks to Google Maps, and we had this massive house all to ourselves!
The hot tub around the back of the property was a real treat but, truth be told, everything there was all that we needed and more. The owners were very friendly and relaxed when we met them to pay for our stay. The decor upstairs is a bit dated, particularly in the bathrooms, but that's in no way an issue whatsoever. It adds to the charm, if anything! The whole place was spotless.
The location itself is also great - you're far away from Brecon for it to be a lovely rural retreat, but you're also close enough for it to not be a trek to get anywhere.
Would happily recommend Sunnyside to anyone.
