Turkey Travel Group is an excellent tour agent! I brought a group of 5 students to Istanbul for a study abroad program. Before coming to Istanbul, General Manager Yasar Celen was extremely helpful when I was preparing the program. Despite the time difference, he was very quick to get back to me with his answers to my questions and his further suggestions for our program. Our tour guide, Ender Boz, and other personnel (including our drivers in our daily excursions) were extremely helpful, attentive, friendly, and nice. Overall http://www.packagetoursturkey.com Turkey Travel Group presented an excellent example of Turkish hospitality during our stay in Istanbul.
