I recently took a two week small group tour of Iran with Mohammad Hesani as our guide. The sights and schedule were fixed, but Muhammad did everything possible to accomodate everyone in the group and was quite flexible. I do not usually travel in group tours, so this was a new experience to me, but Muhammad is mellow and made me comfortable, from the meeting at the airport to the final departure. He gave just enough information when we visited places without becoming tedious and boring. In the end, I felt he had become a friend rather than a tour guide. He has interesting conversations and is very personable. He was able to give great insight into Iranian culture and history. I give him my highest recommendation.
