In reply to Birks:
I stayed there last year. There is a tap outside for drinking water, no idea what the policy for non-guests is, also don't know if you can just buy dinner. There were a few tents not far away, there wasn't much snow or running water about so they must have gotten water somewhere... Don't know how tolorated or not camping is.
Hut was really nice, dinner was substantial, breakfast less so, but we were last up as we were just walking out that day, I suspect it is better if you are up at normal climbing time. Dorm didn't feel crammed, the one I was in had bunk bed platforms with your feet pointing into the middle of the room and each person separated by a half length divider.
No shower, does have toilets and sink though.
You could buy additional snacks and drinks, though expectedly pricey. Guardiennes were very nice, friendly, helpful. You could charge a phone if you asked nicely so long as it was sunny.
