We were so lucky to find Ilker.  He was amazing with our group. He has a vast fund of knowledge and shares in an engaging manner.  His English is excellent. He even took my husband wine-tasting while the rest of us shopped!  He arrived on time and took us to all the sites that we wanted to see and suggested other amazing options. His food choices for meals were delicious.  If you are looking for a private guide in Turkey, he is awesome.
