Great experience with this travel agency - Go Asia.
Tour guide speaking fluent English, and able to communicate in Chinese as well. Our tour guide Mr.Thang is a very nice & helpful person, really enjoy the trip to Tam Coc, If i know about this agency, I will definitely use them for my Halong Bay tours as well, but well... everything was arrange by the hotel & the Tam Coc tour was arrange day after Halong By trip.
Going to recommend to my family as my sister plan to go Hanoi as well and she feel more comfortable if the tour guide can communicate with Chinese.
