Reliable & Good transport provider :) A21 was very responsive to my queries & was able to communicate with me via WhatsApp promptly throughout my stay in Hanoi. We booked 4x Chapa Express train tickets (2 way) to Sapa & Private car (2 way) to Halong Bay. It was a breeze using A21 & strongly recommend using their services. Their prices are also comparable to other local rates.
Used them to book a bus from Ha Long to Sapa, they were great. Answered quickly on WhatsApp, provided a Paypal payment link. Very communicative, good English. Will use again while I'm in Vietnam.
