I was in Iran from 1 to 15 April 2017. Everything from hotel to guided tours was arranged by Irantourismcenter. I traversed from Khoy in west Azerbaijan all the way to Shiraz, covering 10 cities. I went there with low expectation but came back with cherished memory awed by food, people and architecture fused with rich history and tradition. Thanks to Irantourismcenter, everything from visa to transfer to stay went very well.
I will definitely use the same service if I ever visit Iran again.
