Had a great time at Hikmet's apartment, and he is such a warm and friendly person! He arranged an airport pickup for us last minute and when we arrived we received some watermelon, which was delicious on a hot evening, and organised a homemade Turkish breakfast for the next morning. The apartment itself is a great size, very comfortable and is in a central location. While it's not central Sultanahmet, it's close walking distance to many attractions and the tram line. Would definitely recommend!
