Me and the missus did a day with Stuart at ForestFree ride recently and had a good day. Location is indeed in the middle of nowhere but it's a gorgeous setting in a valley and Stu, his wife, owls, dogs and sheep were all really friendly and laid back.
Not sure I got as much out of it as I thought I would but probably down to the GF and I being at different levels and what I was after (jumps) there's only so much technique you can learn before it comes down to MTFU'ing and getting on with it!
We didn't stay in the bunkhouse but did use it for tea breaks and lunch but looked nice n cosy and would take advantage of it if we went back.
