We booked a 7 days tour through Ms. Thanh Xuan. Xuan was so helpful in working on our itinerary, after many emails back and forth we were ready.
All the tours procceded this way. Xuan certainly uses the better tour operaters in every area of Vietnam. We were provided with 24hour phone number if we needed help, for our days we felt we had an angel watching over us in Vietnam. As for the price it was certainly Asia Tour Advisor and value for money and I highly recommend this company to anyone wanting to tour Vietnam.
