We stayed there in June 2013, visiting from San Francisco, and it was great! Hamza is an amazing host and he makes sure you get all you need including transportation, accommodation and any questions you may have about Istanbul. The location is great, really close to Hagia Sophia and the Blue Mosque in Sultanahmed. Walking distance to the mosques, shopping, Turkish baths and more. Definitely a great location and good size apartment for a few nights, just make sure you coordinate your requests with the host and all can be taken care of prior to your arrival. Thanks so much, Hamza! We'll be back.
