I and my family had a 7 day trip to Tibet in 2015. Gap was our tour guide. He is very knowledgeable, and very friendly. He has arranged very well our whole trip, from where to stay, what food to try, the beautiful views and rich culture! We especially value his deep knowledge and his great introduction of the history and the culture. He speaks great English which my daughter likes the most. So she can ask all kinds of questions. It is a trip once in a life time! We appreciate Gap very much for his excellent guide, and highly recommend Gap if you are planning a trip to Tibet.
