The neighborhood runs along the Göksu River and the Bosphorus, offering pleasant waterfront promenades and a selection of restaurants with Bosphorus views. It's a relaxed area with a local feel, away from the more crowded tourist spots. It's an excellent choice for couples looking for a romantic escape with scenic views and a tranquil setting.Kanlıca is another excellent Bosphorus-side neighborhood, famous for its yogurt topped with powdered sugar, which you can enjoy at various cafes along the waterfront. This area provides a quieter, more residential ambiance with Ottoman-era wooden mansions lining the shore.
