Hikmet is a fantastic host. He goes out of his way to make you feel welcome offering you a traditional Turkish breakfast on a day of your choice and placing strawberries and water in the living room for your enjoyment. We didn't arrive until late but he still made the effort to come and greet us. He also arranged airport transportation for us.
The apartment was exactly as pictured and suited our needs well. The beds are comfortable and the apartment is very quiet. It is a five minute walk to the Hippodrome where you will find Hagia Sophia, the Blue Mosque and Topkapi Palace. There are also lots of excellent restaurants in this area. It is a 20 minute walk to the Grand Bazaar and about the same to the Egyptian Bazaar. There are lots of steep hills but you can still walk everywhere.

I would definitely stay in this apartment again and would highly recommend it to others.
