Amazing from Hoi An to Dalat. In the first hours you can sleep, in the last hours you can enjoy the amazing view, in the morning. The bus is like all the others, normal. Price is a little bit expensive. Arrived earlier. About 1h.
Sleeper bus was very clean and tidy. Drivers were very good. We did leave 30 mins late. Make sure you ring food on bus as they dinner stop around 11 at night. Lots of stops on the way
