Excellent overnight bus trip from Hoi An to Da Lat with Viet Lao. The staff was very friendly, the bus was clean, the driver was a good driver, and there was no music or unpleasant noise. All this at a good price with smooth communication in English, so I recommend it. For first-timers: there are no toilets, but there were three stops approximately every two hours (you are notified in advance by announcement). You cannot eat on the bus, but there are restaurants and snack bars at some stops. You must remove your shoes and walk barefoot. At the stops, plastic slippers are provided as you exit the bus; you return them to a bin before reboarding. A small bottle of water, a blanket, and a pillow are provided. There is a USB port. I couldn't get the Wi-Fi to work, but that might be my fault. For those who are overweight or very tall, I recommend taking buses with fewer seats (there were about 35, and I'm not overweight, but it was a tight fit). I recommend the lower and middle seats.

I have taken Quoc Dat bus several times before but was very surprised because the day I went was a holiday but the quality of the trip was very good, on time, correct seat, clean, had wifi, the driver and the bus conductor were very pleasant to talk to. When I arrived, the bus company also supported a shuttle bus to my house. 10 points for the bus company, hope the bus company can maintain this quality. Thank you
