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.

10/10 experience with HK bus lines. We've been traveling for 8 months and this was by far our best bussing experience. What stood out was the high level of friendly customer service, and the comfortable cabins with working charging ports, massage chair, etc. We boarded in Hoi An and the gentlemen working in the office was so so lovely (I believe his name is Qui but I may be spelling if wrong). He was extremely helpful, great attitude, and eased any concerns we had. I would highly recommend HK bus lines and will certainly book with them again.

Will support the bus company many times more, friendly bus attendant, new clean bus departs on time

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

It is very difficult for foreigners to understand the location of the bus terminal and where the buses come from. I arrived an hour before the bus departed, but after walking for over an hour they finally called me and found me. The service was normal, but anyway I slept better than in a hotel because I was so comfortable. It would be nice if the horns were less loud. But I enjoyed it so I give it full marks. Thank you very much.

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.

Shuttle bus driver very good attitude

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 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)

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