Bebek Luxury district, so it would be difficult to find a place here, but not impossible.
ArnavutköyA neighborhood full of charming, old wooden homes. A half hour walk from Boğaziçi University.
OrtaköyLively waterside social area with quiet backstreets of small apartment buildings. Not within walking distance, but only a bus ride to the bottom of the Boğaziçi hill.
BeşiktaşNot within walking distance, but has direct buses to Boğaziçi, and vibrant student culture.
