I originally booked with Hanoi Advisor Travel for a two day Sapa trek and homestay. Wind was my agent and she were so helpful and friendly, coming directly to my hotel to provide me with details of the trip and offering help and guidance on any aspect of my stay in Vietnam. The Sapa trek was great, although it was unfortunately very cloudy, however the homestay we were at made up for the weather - our host made some delicious homemade food. And every step of the way, Wind made sure that our trip was going smoothly.
We were so pleased with her services that we also booked the Halong bay tour with Advisor Travel Agency as well.
I would highly recommend this Agency to anyone who is planning a trip to Vietnam!
