Go beyond the guidebook on a small-group tour of Istanbul’s Old City. The comprehensive itinerary takes you to the Hagia Sophia, Topkapi Palace, Hippodrome, and Basilica Cistern. You’ll also visit the often overlooked Nuruosmaniye Mosque and sample Turkish Delight at the Spice Market (Misir Carsisi). With maximum ten people per group, you’ll have ample opportunity to interact with your guide and get suggestions for the rest of your vacation.
