We took a day time sleeper bus with HM Happycar from Hoi An to Phong Nha. I received a WhatsApp message from the organizer to ensure we found the bus ok before departing. The bus was extremely clean and in great condition. The little bed capsules were private and lay totally flat, or you could put them into a partially reclined position. I am 5'4" and could lay completely stretched out, my friend is 5'9" and could do the same with flexed feet. There was a USB port, lights and air vents. The driving felt very safe and there were two drivers who traded off which helped us feel safe as well. We stopped 3 times for toilet breaks. After getting dropped off and going about our day, we realized we forgot air buds on the bus. I messaged them via WhatsApp and they responded immediately that they would ask their cleaning staff. They found them and organised a nearby hostel for them to be dropped off at for us to pick up at our convenience. Very impressed overall, would book with them again.

We should really support good bus companies like Khanh Quynh, from the attitude of the drivers, staff to the facilities of the bus. The buses are new and very clean. I just hope that Vietnamese passengers will travel in a more civilized manner.

The driver and the conductor were very enthusiastic and dedicated. I got on the wrong bus (same company, same route). The driver and conductor of both buses were very helpful. The ticket price was cheap but the quality was very good, the ticket included a dinner. The bus departed 45 minutes later than on the app, but due to the storm, it rained very heavily, which is understandable. 99/10

Good service - the assistant driver is cheerful and cheerful - the bus company needs to maintain trust - thank you for the experience of the trip!

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

I traveled with my wife from Saigon to Danang. Everything was fine. The bus was new and comfortable. The staff didn't speak English, so we had to use Google Translate. They showed us where toilets were and where to eat. The bus stopped 4 times within our 16-hour trip. We arrived 3 hours earlier than expected. Authentic experience :). The main problem was the company changed our pick up point. They were calling us a whole morning to inform about it but we couldn't understand Vietnamese. The manager in our hotel helped us.

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)
