Accommodation around Ystradfellte?

I’m organising a Welsh end 2 end off road ride in June sort of based on the Sarn Helen route.

I have one accommodation problem, does anybody know of a place or places to take 10 mtb’ers around Ystradfellte on June 17th? Just one night, ‘cos we’re just riding through.

Within a few miles is fine, but I don’t want to go too far off the route.

Thanks in advance

Have you thought of South Wales caving club
