I was excited about the train since it was going to be my first air-conditioned sleeper - such luxury. But it was the same as the others I've been on - just colder and the windows (which were too filthy to see through) don't open. One plus is that there don't seem to be as many people crowding in to one berth. On the other sleepers there would often be two (or three or four if there were some children) in one space - making it very tight for everyone. On this train it seems to be one berth, one person. Oh and blankets and sheets are provided!
