We booked a trip from Hanoi to Cao Bang via Vexere. We left at 9:15 AM, after loading our luggage, although the departure was originally scheduled for 9:00 AM. We had a 20-minute bathroom break midway through the journey. We arrived in Cao Bang around 2:00 PM. The seats are very comfortable, and there's even a lumbar massage function if you want it. A small bottle of water is provided at each seat. The driver drove quite carefully. I recommend this transport company.

Wow. The car was brand new, clean, and in my favorite shade of blue. The driver was incredibly friendly. The shuttle service on both sides was very quick and the drivers were very helpful.
