This is what the little sink area looks like in every small cabin. There are three mirrors, towels, glassware, and even fresh bottles of water. For the record, there's a communal toilet at the end of every train car.
The cabin itself is a little small (so small, I couldn't get a proper picture to denote size); it's comfortable and cozy but definitely pretty snug for two people.
All of the sleeper cars look pretty similar, but each has a different stylish carpet running along its length. The same goes for the fancy dining cars and the bar car; there's uniformity in the style but uniqueness in the upholstery.
