When going to Sapa, I booked Sao Viet, and when returning from Sapa to Hanoi, I booked the G8. The G8 was so good that I felt fortunate that I had booked a different round-trip company. (It may also be because the comparison target was not good.) Although the pick-up service was a bit much. It was late, but compared to the Sao Viet pickup vehicle, which was so dirty that I didn't want to ride it, the G8 pickup vehicle was clean, and since it was a limousine bus, the seats were comfortable. Not only was the sleeping bus itself much neater, I was able to sit in the seat I had reserved, and the seat reclined more so I was able to get in comfortably. However, tall people may find it uncomfortable. The driver also confirmed the drop-off location, so I got off at the correct place without making any mistakes. There aren't many reviews on the G8, so I booked it as a challenge, but I hope it helps :)
