Rough to have 2 transfers for a bus that looked like it didn’t, especially when the second bus wasn’t a sleeper. It was expensive compared to some other options too
These triple row sleeper buses are not for everyone. I am 6ft and could not lie down flat. Had to sleep with my feet by my knees all night. There is also no room for bags inside the bus so best stow as much luggage as you can. Book a VIP sleeper if you can, worth the extra money. You also have to change buses in Hanoi which is not well explained.
