I had hung out on the streets and walked in their office, the staff was very nice and professional. I had an unforgettable experience on a 2-day-tour in Hanoi starting on November 20th. They were my last 2 days in Vietnam. I had enjoyed the trip a lot.Then they helped me booking my ticket from Hanoi to Nanning.They are very efficient and responsible. I'd like to come back again in the future. 很好的旅行，我很享受，也很感谢，这趟长旅因为河内而变得惊艳。还会再来越南，看更多的风景，感受更多的民俗。
