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.

The Vexere.com website provides clear and user-friendly instructions, making ticket purchase quite easy. — Specifically, the Bao Ngoc bus service that took us from Saigon to Da Nang had a very professional, polite, and courteous staff; they clearly guided passengers when boarding. The place where Bao Ngoc stopped for dinner was spacious, airy, and clean. The dinner consisted of 6 main dishes and a bowl of soup for a table of 8 people; there was so much food we couldn't finish it, yet it only cost 50,000 VND per person. And when we arrived in Da Nang, even though our address wasn't updated on the website, the staff still helped us call a taxi and subsidized the fare. We are very grateful and would like to recommend Bao Ngoc bus company to everyone.
