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)

The driver was friendly, he even invited us to eat and drink before we got in the car to continue.

The first time I went from Nghe An to Da Nang, I was a bit worried that the bus company was cheating me, but in reality it was very ok. The bus company was friendly, the operator called to confirm and remind me of the schedule to avoid missing the bus. 10 minutes before the bus arrived, both the driver and the operator called. All information about the license plate and the driver's phone number matched the email received. I kept the seat I booked for myself. The bed was spacious and comfortable, the bus ran smoothly and had no smell, and I arrived in Da Nang almost 1 hour earlier than the scheduled time. 10 points, next time I need to choose this bus company to go from Vinh <-> Da Nang

Good service, clean and fully equipped, good service attitude, happy and comfortable.
