Deniz is an amazing host! He can give you many useful tips and make your experience in Istanbul unfogettable. We went to one photobook festival where he was showing his work (which is very interesting and also he has a lot of exciting stories about it) and also to one other festival with street musicians and other interesting things connected with traditions and the local life. It was truly authentic experience which is hard to have without somebody like Deniz who even taught me how to dance (I will practice more before going again to Istanbul, Deniz:)))
