Semih was an excellent guide, he opened up the city (“his” city) in ways we never could have experienced on our own. His depth of knowledge was remarkable, explains the many diverse historical levels from Istanbul’s early beginnings from the Eastern Roman Empire to the Ottomans to the present day. We did two days with Semih and could easily have continued. He was personable and funny taking us to corners we never could have found on our own. As I write this I am flat out exhausted but with a full and happy heart. I wish I could give home more than 5 stars ⭐️. If he is unavailable change your travel plans. Bravo Semih.
