I took a sleeping bus on my way here..Well, it was a fun experience, and I came comfortably. However, the driving time was too stuffy on the road, so I found a limousine bus. I heard that the driving time was 5 hours, but I didn't make a lot of honking sounds.. My goal is to achieve it. If it's daytime and you don't have to sleep, it's highly recommended. But the usb charging of the air conditioning/seat is random. It would be satisfactory to check that, but isn't that the same for sleeping buses:)

No reckless driving from Ha Giang to Quang Ninh, but good and calm. Friendly staff. Complimentary water and good WiFi. Beautiful bus, spacious bed. I really enjoyed the ride!

This trip was good. It probably depends on the bus conductor. If the quality is maintained well like this, I will recommend and support the next trip. The sleeping compartment has a very smart place to put your phone and charge it, and a place to put your shoes. Other buses have not seen this.
