We toured the Historic Core of Istanbul with Safiye in late April and had a wonderful day. We took the Tram into the Sultanahmet district from our cruise port. She was a very knowledgeable and organized guide and as promised we skipped the major entry lines to the Sofia Hagia, Topaki Palace and the Basilica Cistern; she knew the best time to take us to the Blue Mosque! With her expertise guiding, we learned a lot about what we were seeing! I can highly recommend Safiye; she was a delightful guide!
