"Prachtige uitvalsbasis nabij de Brecon Beacons"

8.0

Prachtige uitvalsbasis om Brecon Beacons te bekijken, een hike te maken naar de Pen y Fan en watervallen te bezoeken. Het Engelse ontbijt wat vers voor je bereid wordt was top!

Temperatuur douche niet in te stellen. Te warm om eronder te gaan staan.

9.0

Breakfast was amazing - partaking of every offering (almost) kept us going for the whole day. The room and ensuite had everything necessary. Great for access to nearest town, major roads and places of interest Host and staff were delightful and very accommodating
