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.

This was the first time I drove a long distance but felt like a short one, the car drove as smooth as a Samsung and the seat was like a cool, air-conditioned bed. Initially, the car had a problem and the driver reported being late, but he handled it and came to pick us up as scheduled on the system. The driver, Van Si, was so funny and enthusiastic that despite the wind and rain, he transported us safely to our destination. 5⭐️ for driver Van Si and the garage. Next time, I hope to have the chance to meet you again.

Lovely and enthusiastic staff. No shuttle to the pier but dedicated shuttle home.

Bus quite nice, but didnt have pillow, didnt get assigned seats, and was more than 1 hour late, but that didbt matter because of good driving, nice staff, and quiet atmosphere to sleep! Overall happy as i was able to sleep well!

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.

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

At first I was scared reading the reviews but it was ok ((((= the driver was happy and friendly and carried my things carefully
