I stayed at Omasila both before and after a winter trek in February. Like everyplace else in Leh, except the Grand Dragon, Omasila lacks central heat and running water and has electricity only a few hours in the morning and evening. And it is COLD. Despite that, everyone on the staff turns themselves inside out to do whatever is possible to keep you comfortable, including hot water bottles, buckets of steaming water in the morning, endless thermoses of tea, etc. And always with a smile. A very pleaseant experience under very trying circumstances.
