Everything as expected.
You just have to wait outside opera house, no sign, no people there to ask, just wait.
The driver was good, a few danger moves on the road and a lot of horn. Like the average in Hanoi.
The van is very comfortable. He dropped me in the hotel.
The bus was very comfortable and we were very punctual.
But the driver drove very fast and kept making overtaking manoeuvres. A woman had to throw up and the driver still didn't slow down.
Unfortunately it was very difficult to contact the bus operator. Entering the pick-up and drop-off point was not possible with 12GO.
We booked a van from Hanoi to Mai Chau. A ended up driving in a small car cramped with other passengers. I had to sit in the middle and finished the journey with a back pain.
The driver was very nice and he drove well, but we were 7 people in a car and we were tight. I was in the middle on the bench which was not comfortable. We arrived at our destination an hour after the scheduled time, as often.
They provided excellent service. They asked if it was possible to change my trip time, and very kindly , they picked me up at my accommodation to accommodate the change. The vehicle was clean and comfortable, and the air conditioning worked perfectly. The staff was very friendly.
