Istanbul is known as the City on the Seven Hills. So, while Sultanahmet seems compact, arranging transportation makes sense. On this day tour, travel in a Mercedes Sprinter minivan direct from your door. See the Hippodrome, the Blue Mosque, Hagia Sophia, the Grand Bazaar, Topkapi Palace and the 6th-century Hagia Irene church. Entrance fees are included (Harem admission costs extra) but food and drink are at your expense.
