We had the most incredible 2 days with Hanifi! Not only is he an incredibly kind and patient man, he is extremely knowledgeable about all the places we went. We had my 80 year old mother in law with us - she's in good shape, but he made sure the tours were especially comfortable for her. The private Mercedes runner van was spotless and very comfortable. I can't recommend Hanifi enough! He took us to a great cafe for lunch - the food was amazing and we got to try new dishes (turnip juice is pretty good). He was our guild in the Grand Bizarre and made sure we were able to meet up with reputable vendor. Had an incredible time and cant wait to return to Istanbul!
