They go the extra mile. They picked me up at the airport in Sapa, and when I told them I was going to a hotel close to the airport, they dropped me off close to it. :) I was expecting to be dropped off at the airport, and walk from there, so it was a nice surprise. There is wifi in the bus, USB chargers. They make 2 toilet stops on the way.

The car runs on time, the service staff is enthusiastic and friendly, and returns at the right place
