Istanbul bridges continents and centuries in ways that require adjustment. The Hagia Sophia and Blue Mosque attract crowds that patience or early mornings avoid. The Grand Bazaar exists for tourists primarily; the Spice Bazaar mixes more genuine shopping. Trams and metro cover major areas efficiently on Istanbulkart — buy and load immediately. Taxi apps prevent the meter manipulation street hails sometimes encounter. Prayer times affect meal service at some restaurants and all mosque access. Tea culture exceeds coffee here — çay appears everywhere, usually free or nearly so. Carpet sellers target tourists aggressively; polite but firm "no thank you" works. Asian side (Kadıköy, Moda) offers less tourism and more genuine neighborhood life. Bosphorus ferry rides cost the same as transit tickets and deliver unmatched views. Haggling applies in bazaars but not fixed-price shops; reading context matters. Rooftop restaurants with views charge view premiums — sometimes worth it. Day trips to Princes' Islands escape city intensity entirely. Data connectivity requires proper SIM cards as WiFi can be unreliable. The city's size demands prioritization; you cannot see everything in one visit.
