Recommended - on time and changed my return ticket swiftly (once I found a local person to call, a worker at the Huu Nghi Bus Station. Bless him). I was getting pretty frustrated why the driver is not coming for my return to Hanoi, only to be told that I actually booked the next day by mistake. The office sent a driver in an hour and only paid the upgrade to limousine, as that was the scheduled mini van. Moral of the story - double check before booking, preferably if you are not groggy.

Comfortable and felt safe. I have been on many overnight busses through South America and this was a far superior experience. Comfortable bed / seat, relatively easy to find the bus and get on board despite the language barrier. Bus staff were friendly and very helpful. They even dropped me as close as they could to my hostel
