We did a tour with Angkor Wat Services and had Channa as our guide. A very professional company and an exceptional tour guide - by far the best we've had in all of our travels around Asia, and that is saying something, because we have had some excellent tour guides!!!!
Channa was so knowledgeable!!!! But not only that, she was incredibly fun and friendly and shared her knowledge in a way that was interesting and easy for us to understand. By far and away the best tour guide we have had so far. She really brought Angor Wat, Tom and all the other places we visited to life. We only wished we had her as a tour guide for a longer amount of time.
As for John at Angkor Wat Services - very professional, replied quickly to emails, and on the first day I had an issue with my bank and he very kindly allowed us to sort out the issues with the bank that day and do the tour the next day instead. We were very, very impressed by this outstanding customer service and highly recommend his tour company to other people - because of this and his exceptional tour guide, Channa.More
