Good idea. Haven't overnighted but have eaten lunch there, and thought it was a lovely place with friendly staff, and much closer to the major bouldering areas than anything in the main valley.
Even though it's accessible by road it's actually an ÖAV (AAC) hut, so I guess standard hut prices would apply.
