Berghaus Diavolezza, Pontresina. 60€, including a 4 course dinner and breakfast (plus the obligatory ride on the cable car: 27€)
First and only hostel stay during the trip. The regular rooms were meant for 2-4 people and the price for just 1 person would have been about the same as for much higher number of people, so I decided that the group accommodation was a good compromise. This being low-season, I ended up having a room of 3 double-decker beds all to myself.
(And since there was no mirror in the room, the obligatory self shot is taken later on the ride back down to the train stop.)
