We met our guide, Metin, at 9:00am beside the Hagia Sophia, and spent the next 7 hours walking around the old city and all the main sites. If you are in the city for a weekend, this tour is a good way of seeing the key historical sites. In the morning we visited the Topkapi Palace and gardens, the Blue mosque and the ruins of the hippodrome. We stopped for lunch in a cafe overlooking the Bosporus, Blue Mosque and Hagia Sophia- beautiful on a sunny day. In the afternoon we went to Hagia Sophia, Spice Bazaar. Our guide was really good humoured and informative. Great intro to the city!
