Is Grab operational in Hanoi?

In Hanoi, my means of transportation is Grab. From being afraid and cautious at the beginning, to being at ease with everything… Taking a car is convenient for chatting with the driver, and riding a motorcycle makes you feel more integrated into the local community; and most importantly, most of the time in the car is a free practical Vietnamese speaking lesson for me!
