Sultanahmet's historical core + Beyoğlu's contemporary depth + a real Asian-side food scene.
Istanbul is the rare city that's literally split between two continents — the European side holds the Sultanahmet historical core (Hagia Sophia, Blue Mosque, Topkapı, Grand Bazaar) and the modern Beyoğlu district; the Asian side (Kadıköy, Üsküdar) is where most locals actually live. Four to five nights is the right scale, and the trip is significantly better once you accept Istanbul as a megacity rather than a compact historical capital.
