The car was adequate; we rode the same comfortable bus the entire way. The only thing I'd say is "aww" is that the air conditioning is on very high, even with the individual vents closed. This is the case almost everywhere in Asia. So, bring some warm clothing or something to cover yourself with.

I left my camera on the seat on the bus from Yen Tu to Hanoi. I only realized it three hours after getting off the bus and called the driver in a panic. Luckily, the bus company staff were very helpful. Many thanks and best wishes to the Tùng Tuấn bus company staff for good health and safe travels!

The driver for this trip was very nice!

The bus is a standard model, so it isn't the newest, but all the services are excellent. Two drivers take turns driving, ensuring safety. The manager is friendly, and the three staff members take good care of foreign passengers. It has air conditioning and USB charging, and the bus stops frequently at rest areas. The restroom fee is 3,000 VND. There is a variety of snacks available. You just need to wait inside the bus terminal for departure, but due to delays, the journey takes about 9 hours. I am satisfied with the 480,000 VND bus.

Honestly, the best bus ride I've had so far has been Mong Cai to Hanoi from 11PM - 6AM. Staff were polite and helpful, and unlike other rides, it was easy to sleep, because the driver wasn't constantly honking. I woke up at 4:30 AM in time for a bathroom break, and the facilities were clean. It's definitely a budget bed, but as a short queen at 159 cm, I was able to fit with my shoes and backpack. USB port works, and with the Viettel 8 gb/day plan, I had plenty to keep me entertained. Water is provided, and the only real negative was a loud auntie on her phone. (not much to do about your neighbours!)
