My husband and I were in Egypt over Christmas and part of our trip was the sleeper car to Luxor. We absolutely loved the trip. Let me see if I can dig up some of our photos so you can see what it looked like...
Okay, here are some pics. They're not the greatest but you'll get a sense of what the cars are like...
In that second picture, my feet are touching the other side of the car, so they are not spacious but we found them to be perfectly adequate. Not fancy, but we weren't expecting fancy. The staff were absolutely lovely, very kind and helpful.
