In reply to J1234:
I get the bit about something special way above the predictable Trip Advisor standard criteria - I've stayed at Tranearth and it required a bit of a slog on foot to bring enough beer and food for a few days, and that's character-forming and adds to the isolation experience. The Bowderstone Hut, which used to be leased by the NMC, was similar - no convenient parking, but a great location and a charismatic place to stay.
For huts with easier parking for the idle or time-pressed, Cefn Goch, the Gloucestershire MC hut in Deiniolen was a well-run club hut, as was Carslwark Cottage belonging to the Derbyshire Pennine Club in Stoney Middleton - both really well looked after, thoughtfully equipped and in excellent locations.
In all the huts I've snored in over the years, its mostly been the company rather than the accommodation that's made it memorable.
