We took the tour with Happy in May 2014 and had a wonderful time. The thing that I liked best about Happy as our tour guide was that he had great positive energy and was very informative about the location we were in. We didn't have a problem with communication, he spoke very good English. He did a wonderful job overall as our tour guide and now that I know he also does a tour in Da Lat, I will definitely book him for another tour :)
