Hanoi to Ha Long trip. A driver contacted me through WhatsApp to coordinate my pick-up from my stay, then when we got to the office, I was transferred to the limo van and off we went, with a short 15-min roadside stop for restrooms and purchasing snacks. We left a little late but the whole trip still only took about 2 hours so I was happy with the efficiency.

Great experience, best limousine so far. The only suggestion is to have some be quiet policy, like Vin bus for example. There was one woman who didn't stop yapping loudly either on her phone or with the driver. Driver was respectful. Other passengers, even small kids were very considerate as well. I'm going back to Hanoi in a few days, we will see if I was just lucky or the limousine and the service are always great. For now, definitely recommend
