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.

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 female receptionists were lovely. The male staff at the university office were cheerful, caring, and enthusiastic. During my trip, there were two elderly families talking quite loudly. When a staff member reminded them to be quiet, the two elderly people scolded her. If they had given a bad review, I would have responded in kind. The staff member's reminder was very accurate. The two elderly people were talking very loudly, so loudly that I even dreamt about their conversation. So, if the staff member receives a complaint, please don't deduct their salary. If they do, please tell them to contact me at my phone number, and I'll assist them. My number ends in 666, the trip was from the university to Nha Trang on January 16th. Oh, and the lovely female receptionists even changed my single room to a double room and added a note saying (I'm alone) in love. But sleeping alone in a double room means every time the bus turns a corner, it's a disaster! I don't travel by bus often, but it's enough to give it a 10/10.
