Kadikoy (Kadıköy), Turkey

At 25 km2 and with a population of 467,919 (2023), Kadıköy is a bustling commercial hub on Istanbul's Asian side. Despite ranking 1st on Turkey's Human Development Index, the district's crowded streets and heavy bureaucracy can be a persistent headache for residents. Kadıköy's lively cultural scene, with its numerous bars, cinemas, and bookshops, makes it a magnet for Istanbul's liberal elite, though the working-class ambiance and lack of high-end nightlife may disappoint those seeking a more glamorous lifestyle.
