Stayed here as part of a team build. There were 16 of us split in the two dormitories available. They can sleep up to 23. A warm welcome was given to us by the family that run the accommodation and nothing was too much trouble. It was lovely and clean and spacious with a well equipped kitchen, however in the town of Llanidloes there are several eateries if you so choose.
You don't have to book the whole of the Bunkhouse, they take bookings from individuals as well as groups. It is ideal for ramblers as The Bunkhouse is situated directly on the Glyndwr Way and The Source of the Severn is close by. There are facilities for cycling, golfing and clay pigeon shooting and sailing at Clywedog dam. There is also an outdoor pursuits centre nearby.
I enjoyed a wonderul night's sleep as it was so peaceful and tranquil. I am seriously considering returning for a weekend later on this summer.
