I wanted to share w/ you yet another glowing review for Bryan. My friend and I contacted him through TripAdvisor and his communication was timely, informative and very professional. We only needed his service for one full day and he worked w/ us to make sure we had the most productive (and fun) day possible in Xi'an.
He was prompt, courteous and super accommodating. He is very knowledgeable in all manners of the sights and history of Xi'an and I not only learned a lot but also had a blast doing it. His English is excellent and will work w/ you if you need any help in translating or understanding anything.
He is also a bit of a foodie so it was a great match for my friend and I . He gave us great pointers on where to eat near our hotel. I miss that food dearly.
If you're looking to hire a tour guide for Xi'an, look no further. Send Bryan an e-mail and book him immediately before someone else does.
Enjoy and have a great time in Xi'an!
