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.
