Question:

how much approximatelly should we pay for a taxi from Imam Khomeini airport to central/south Tehran (we arrive 4 am)? Is it possible to pay in USD?

Answer:

The approximate taxi fee from IKA to central Tehran with Yellow Samand should not exceed 20$. But if you take a Toyota it will be more expensive.
It is recommended to pay in Toman since all the prices in Iran are quoted in Toman not Rial!
