Everything is very good and safe. There is only one point: the driver and assistant smoke in the car, which can be somewhat understood due to the long distance travel.

I get carsick but the first time I saw a bus, I didn't smell any gasoline at all. It was very comfortable. Surprisingly, the bus company provided meals along the way for all passengers. For the round trip in a few days, I will still choose Huy Cuong bus because the ticket price is only 800k, cheaper than other bus companies.

Good service from Da Nang to Kon Tum. Water, blanket and pillow are provided. You can recharge your electronics with usb plugs. There were some occasional stops for gasing up/picking up people so you could arrive a bit later than described. (Note: we understand and spoke a bit vietnamese)
