What a great guide and a wonderful person. We had a few handicaps as I ended up unable to walk when in Istanbul. He was very flexible and helpful in arranging for me to see two of the most exquisite sights by wheelchair. (And I had my small service dog with me as well).  Beyond personality, Metin has a significant knowledge of the history, dating far back to the origins of religion and other cultural aspects,  of Turkey.  I highly recommend Metin as a guide and resource  when in Istanbul. I only wish we had had more time with him. 

A full day tour with visits at The Hippodrome, Ayasofia Museum, Basilica Cisterns, then lunch and the tram and metro to The Taksim Square and finally a walk through Galatasaray to Galata Bridge passing The Galata Tower. Metin Koca has a great knowledge of old times-Istanbul, and he was able to tell about in a very understable way, so it all became very interesting - especially was the visit at The Ayasofia Museum and The Basilica Cisterns interesting and impressive. Metin was also able to communicate with everyone in our group, and that made the day nice and cosy. Our group can give Metin our best recommendations.

Metin is a great guide - he is super knowledgeable about the history of Istanbul and passionate about the culture and history of the city. We felt very relaxed with him and he has a very friendly personality. We visited all the things we wanted to see and enjoyed the tour. Dave & Coral

A while ago I went with my mom to istambul for a few days . Metin (Martin) was our guide . Despite being told by the people of the hotel reception that I was in a wheelchair he willingly accepted to join us on our tour around Istanbul . He took us to visit the most important sights of this wonderful city : The Hagia Sophia Mosque , The Blue Mosque , The Topkapi Pallace and the Grand Bazar . These landmarks of the city were all very imposing and Martin gave us some very interesting historical information about each of them . Martin Is a very Knowledgeable person. He is very open and friendly and has a kind soul . I have much respect for him . I would kindly recommand him to any tourist or group of tourists planning to visit Istanbul. Thank You very much for your time and kindness Martin - Jamie .

Metin greeted us at our hotel and made sure we didn't miss any of the sites we were hoping to see. Very knowledgeable and easy-going. He showed us a cute restaurant for lunch and made sure everyone was comfortable and happy throughout the day. In only one day on foot we covered a ton of ground. Great guide, highly recommended!
