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.

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)

review of a trip to experience the premium double room car service: + The car rides smoothly, cold towels and cakes are served. At first I thought it would be charged but when I asked the staff they said it was free, so I asked for 2 seats. Delicious + Professional staff and driver, use very good app, collect money with QR code to scan, no need to discuss + The fenders on the car are still very new, it seems like the car I drove was newly purchased, so there is still a plastic bag Yes, this bus company invested a lot + in general about the service, I rate it 9.6/10 - The car goes a little faster and it's ok, the transfer goes a little faster to help reduce detours and it's ok, everyone should choose and experience it. Try it out, no need to fly and waste money
