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:)

Got to my destination safely and on time. Convenient stops for food . Overall a very efficient service . Will be using this company again during my time in vietnam

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!
