Asia Tour Advisor was their easy going friendliness and helpfulness
I highly recommend contacting Ms. Huyen and her colleagues when visiting Hanoi and the surrounding area. I booked a Halong bay boat cruise with them and it was great. I met a number of people that went on expensive tours with other companies/hostel vendors to Halong bay and had truly nightmarish experiences. Ours however went perfectly and was very reasonably priced. What was really great about Asia Tour Advisor was their easy going friendliness and helpfulness. They were happy to go out of their way to assist you with things, and not just looking to profit from your lack of local knowledge as a tourist. This was in stark contrast to other vendors in certain hostel lobbies that were scamming tourists left, right and centre.
