I am Hans, from Germany. My wife and I went to Iran last year in October, employing very pro private tourguide named Mehdi. He is kurd, from Sanandaj but is available throughout Iran. He picked up us at the Imam Komeini airport on time, so we found out he is so obssessed over punctuality. He is dependable, flexible and professional, used to be helpful all the time with us.The trip took 24 days, we had great time with him, energetic, reliable and certified. Highly recommended.
