Extremely knowledgeable of his history. A pleasant personality. Only complaint would be the amount of time spent being taken to shops after actual tour. One or two would be enough. I would recommend Oguz to any of my friends travelling to Istanbul.
TOUR GUIDE RESPONSE: Meeting you was a pleasure and I feel sorry for the shop reference:) These stores have some Istanbul treasures beyond the merchandise (we were stuck in none, just kept moving). One shop showed us a surprising Byzantine feature - the 2 columns of a Roman-Byzantine palace and a 4th century AD column rising from the basement Another showed a 6th century Byzantine cistern and Istanbul overview. As well we went to an art store - Istanbul drawings book you wanted to see.
