Experiences living in Istanbul

I have been living in Munich for over 1 and a half years now. I love it here.
I have recently been offered a job in Istanbul. Was wondering whether there are any Toytowners out there who have experienced life as an ex-pat in Istanbul and if they have anything to add that will help me with my pros & cons list.

Thanks all!

Been there on business several times, and always loved it. Go there for a week or two and get a feel for the place. It's not like Turkey, just like Munich isn't like Germany, and London isn't like England. Big city with its own feel and flair, you might hate it, you might fall in love with it. If somebody offered me a job there, I'd take it.

Wicked town! One of my favorites. Yes, very busy, big, and not like the rest of Turkey. I have an American friend whom went there for 2 years and now she's on her 6th year. She loves it. From our conversations, it sounds like the biggest suggestion would be to start learning the language. You can't find as many people whom speak English there as do in Munich.
Good luck... what great fun!

Thanks Dimmer and Strawberrystar!
I was there for over 3 weeks over August for work. And I loved it! That city is so alive. When I returned to Munich airport, I was so agitated by how quiet it was (and cold).
Turkish might be easier for me to pick up that German. In the 3 weeks I was there I learnt to count to 10, the basic greetings and alot about the foods. Also helps that my background is Greek and alot of the food is the same.
I love the calm and secure life that Munich offers me. But the position I have been offered in Istanbul is great for my career.
Will have to start researching the ex-pat situation in Istanbul. I just hope they have their own wonderful Toytown website...

Cheers!
