Are there any common pitfalls for non-Turkish speaking visitors to Istanbul?
It is obviously harder to get around without knowing the language – then again many Turks do have a basic command of English and will often go out of their way to help you. German can also be heard in the city. On the more negative side, the chances of being ripped off when using the transportation system or when shopping is greater. One piece of advice: Haggle! Haggle, and try to bargain. Also try to find out the “real” price of something before you start to haggle.
