Travelling from Germany to Iran, I'm looking for the cheapest but comfortable way. One idea is to travel to Turkey then going to Iran form there. There are many flights with reasonable price for Germany to Turkey (easyjet). Unfortunately, I'm unaware of such flights for the second part. What's a good way of travelling from Turkey to Iran?
Also, I'd like to add that duration is an important factor as well, taking 4 days just from Istanbul to Tehran is a very long trip and I wouldn't even try it.
Do I need to learn to speak Persian/Turkish for this trip?
