This company was recommended to me by a friend and I was not disappointed. My husband and myself and 2 friends were on a cruise which called in at kusadasi(Ephesus) and Istanbul .The tours on the ship are pretty expensive and not always exactly what you want to see. Both tours we booked through Ertunga were tailor made to our requests and we had an executive mini bus for the 4 of us. The guides were extremely knowledgable friendly and spoke excellent English. I would definitely book with them again if we visited Turkey again.
