Very Good

We had a great stay. One of the best value hotels we’ve ever stayed in. Yes it could do with some TLC but for the price we paid, more than happy. Great breakfast and the spa was super.

Food was good excellent as were the staff but the hotel rooms badly need updating
This was a short break for us, just two days. Food was really good with portions rather too large for us pensioners. Great choice at breakfast. Lunch menu wide ranging: we had home made fish finger sandwich with chips, only £10. Puts Warners to shame. Will go again. very convenient for trips out, eg Steam railway and Brecon canal trips.
It was nice to hear the distant sound of sheep and the gushing torrent of a river

Staff were brilliant, rooms have been let go from a maintenance point of view. Food was tasty but very over priced, especially the breakfast. Would have made a complaint if I’d had to pay £18 for that had it not been included with the nights stay. Drinks reasonably priced though.
The locations is incredible, quiet under dark skies. Rooms are big, quality furniture and have the noise of the river to fall asleep to. Highly recommend.
Great food , great pool ,good staff ,great location for the Beacons . Our room could do with a new coat paint and a tidy up.no stand up shower just a bath with hand held shower.

Friendly staff. Amazing breakfast room was spacious.
We have been staying at Nant Ddu for a few years now and really enjoy the food, swimming pool and hospitality. Breakfast is delicious. We have stayed in several of the rooms and always comfortable, clean and quiet. The only niggle is small things like. Nowhere to hang your coat, towels or wet bathers in the bathroom and only couple of hangers in small wardrobe. We only stay a couple of nights, so storage not too much of a problem, but just tiny things like pegs on back of doors and perhaps towel rail in bathroom would make a big difference.

Nice looking hotel in a lovely location. It is conveniently located in the heart of the Brecon Beacons National Park making it ideal to get out and about either walking, hiking, and cycling in the surrounding area.
Waterfall country is about a 30 minute drive away.
Very friendly and polite staff.
Food was on the slightly pricey side but it was excellent quality.
Can’t comment on the pool, spa or gym facilities as we did not use them.
The hotel ceilings as well as the room we stayed in whilst comfortable and included all the amenities you could possibly need it does look worn in places and needs some work done.
