I went to Teheran last summer.
It was interesting.
Museums, parks. Eating places.
Milan Tower, Golem Palace. And lots of other interesting places.
Great view from the mountains.
Traffic is horrible. But that it how it is in a big city.
Very hospitable and friendly inhabitants.
The English language is not a part of school.
So not so many speak it.
Fortunatly I knew som people in Teheran. They were my guides
I will go there again.
