We upgraded to the most expensive suite they had. The Queen Suite.
The room and the bed were OK, the noise however was terrible. It looked like permanent gunfire next to your head. Only during the 4 hours in the middle of the 8 hour trip it was OK. The rest was awful. Never again for us!!
Straight forward enough to navigate. The train journey wasn't the most smooth in terms of ride comfort. Beds were hard but did the job. I'm quite tall so didn't have to crap up too much which was nice. Air conditioning was a bit weak, ok if you were on top bunk but lower bunks felt a bit stuffy. Did the job.
Comfortable private Room if you book the 2x cabin. The snacks are not enough for the 6h. No toiletpaper, no soap. You have to bring your own food, becouse the menu on the train is very limited (instant noodles shrimp flavor was the only non snack food . The rest was chips and cookies). Still better and safer than the Sleeperbus.
There were no temperature dials or plugs in the top bunks but we managed a good nights sleep, the beds were relatively comfortable and there wasn't too many jolts on the tracks. We also got free drinks and snacks!
Nice stay on demitran train, clean cabin, fresh beddings and clean bathroom. Small passage or hallway but quite good. Passengers with big luggages have difficulty in carrying it inside the train as there is no staff or laborer to carry and besides it has no ramp for luggages to pass on. We love the taxi because it was like a coaster so comfortable and the driver is friendly. I believe vietnamese people has to learn basic English for better communication like drivers, attendants, hotel workers.
