We chose Ertunga based on the reviews on trip advisor and we were not disappointed. Ertunga met us right outside the cruise port at appointed time. I immediately liked him as he was polite and courteous. He spoke excellent English and we had no problem communicating with him, We had hired him for a whole day private tour of Ephesus and surrounding areas.
He is very knowledgeable as a guide and he explained the history of all the archeological sites in detail. He answered all our questions and also provided a lot of background on Turkish history and culture.
He used a large van for the tour and it was very specious and comfortable for the 4 of us. By the end of the day, we became friends.
Highly recommend going with Ertunga if you are in Kusadasi. You won’t regret it.
