Muhammed is the perfect host. He is very very helpful and hospitable. He asked several times if we needed anything, and he even organized our transfer. Communication was also perfect with him. The apartment is in the center, 5-10 minutes from Grand Bazaar, Hagia Sophia and Blue Mosque-it couldn't be better. It is small, but ideal for a couple and for travelers who only spend some time there at night/in the morning. I would highly recommend this accommodation!
