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.

First of all, let's talk about the car. Everything is as convenient and comfortable as the pictures and information I found. Clean, comfortable, odorless, everything is very pleasant. The driver on my trip was very gentle and pleasant. Especially: my family forgot something on the car, we contacted the car company and got it back the next day. Overall, it was very good. - I booked a ticket and was able to choose a seat, so I went to the exact location I had chosen. BUT THE MINUS POINT IS THAT I have a small child so I deliberately chose a departure time with a 22-cabin car (with WC). But when I got on the car, it was a 24-cabin car (without WC). I feel very sorry about this problem. Families with small children should consider and choose the right car. However, I still rate this trip 5* because the whole family went there and came back safely, which was ok.

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

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

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.
