Mehdi at Yadz is a wonderful and helpful guide, and took great care of me when I had the ankle accident, even asking his friend to visit me when he was tied up, although he rushed to the hospital quickly.
Darius is very knowledgeable since he's a professor in history, and I learned a lot from him, and he is very helpful.
My favorite guide for the trip is Hojat from Esfahan, mostly because I spent the longest time with him, and he really brought me to a lot of places in Esfahan and even to meet his talented son, and I learnt a lot about Iranian culture from him.
All in all it was a great trip because of the guides and the people. I have posted some of my Iran photos on my Facebook page "Alex Bluefishcake", in case you need to convince future tourists what a beautiful country you have!
Oh, and thanks for the present. Take care,
