You can sleep inside the airport terminal. http://www.sleepinginairports.net/mideast/tehran.htm >At night most of the people sleeps on the floor over newspaper sheets and there is no exception for tourists. And because of the strict rules in Iran, I can say that Airports are the most safe places in the country. I had a perfect sleep there. mido
