Last year in the Bernese Oberland we didn't wash for a week. There was no water for basic hygiene. This year we stocked up on antiseptic gel and I led a short tour in the Stubai Alps. At the Dresdner and Amberger huts we had a private room for the 3 of us, an eat-all-you-like salad bar at dinner, and hot showers.
I am not advocating adding a comfort factor to the ESC grading system. 
However, out of interest, what is the most comfortable hut to hut tour you have been on, based on accommodation quality in mountain huts. (Valley-based trips from ****** hotels don't count!)

The Ortler tour has the best huts and food that I have experienced so far, sometimes called the Capuccino tour. The group often starts at the Rifugio dei Forni which is a like a hotel, and reached after a winding narrow road from the valley. The Casati, Pizzini (which has a sauna !), and the Branca huts are all welcoming and have great Italian food.
