We went by bus at 19:30 Danang - Nha Trang. The blue illuminated bus looks like a spaceship of the future. Super comfortable! If possible, take the top bunks, and in the middle of the cabin (at least the second row from the drivers, because they can smoke and chat the whole trip) and at least the second row from the toilet (it may smell). We had a clean, comfortable toilet, modern leather seats, and blankets. The driver drove moderately, did not honk excessively at night and did not brake sharply. We slept well) at 4:30 we arrived at the station near Nha Trang. There everyone was asked to get out, given their things and put into a Sprinter, which went to the center of Nha Trang. Due to the fact that this nuance with the transfer was not agreed upon in advance, it naturally raised many questions from passengers. But the drivers don't speak English. They only show you with gestures where to go)) And they literally forcefully transfer you into the sprinter so that you don’t get lost)

For me personally, everything is ok. The driver called back to report the time the car arrived at the pick-up point and after the trip, the bus company called over for customer service. If possible, there should be wifi for guests to use.
