Necdet was fabulous - prompt at meeting us at the hotel and kept us on point all day. He was extremely knowledgeable of Istanbul's and Turkey's history. We were a group of 7 and he kept us all focused and we did a whirlwind tour in 8hrs - totally flexible on our site/shopping visits aswell - he was able to use his "Licensed Tourist Guide" experience to expedite lines. Great day out and we achieved a lot in one day - well worth the cost. Thank you - Tampa Bay, Florida clients.
