Hikmet was really an amazing host, always available and ready to help us. The apartment is very comfortable, and it is located near the Hagia Sophia (walking distance). The roof terrace is amazing, with a wonderful view of Istambul and the mosque next door, and a very nice place to drink tea and smoke shisha while chatting with Hikmet and other people in the building. I would highly recommend this place and I hope to visit Istambul soon again!
