A history lesson and amazing sites.
Guide was excellent. The mosques were amazing. The Nicea ruins were in a town not regularly visited by tourist. Lunch was at a local Turkish restaurant was excellent. Turkey needs to step up and preserve this site.
The Green Mosque was a site to behold. Well worth the trip.
Cenk Akbostanci is a great guide
I have visited Istanbul with friends several times and wanted to see signature places and discover the culture. Ordered private guide tour which was lead by Cenk. He was great - very knowledgeable about the history. Even through our time was limited we saw everything we wanted and figured out many interesting Istanbul stories.
I strongly recommend Cenk as great guide.
