My family and I enjoyed a 2-day guided tour of Istanbul in December 2012 with Erkut Aldeniz, a professional travel agent and tour guide. Having such a short time in Turkey and having four children ranging in ages from 7-14, we were worried we wouldn't be able to see much, but we were pleasantly surprised! We saw most of the major attractions of the city plus a few hidden gems that we ourselves would have never found. Erkut was highly knowledgeable about the history of the city and about Turkey in general and we felt he made our trip something to remember. The kids had a great time and we created many memories. As an added value, Erkut is also a food blogger, and if there's one thing you want to know when you go to Turkey is where to find the best food, from coffee to lokum (Turkish delight). I would highly recommend his services to anyone wanting to get the most of out your trip to Turkey.
