Mustafa's place is a nice abode, perfect for long stays where you can relax and still be close to the Istanbul's nicest venues. Plus, place is better then the photos. Although I stayed for only a night, I got myself a very calm evening for reading and doing my work at the terrace. In the morning, I made myself some tea, stayed in, to enjoy the terrace some more. Definitely recommended. A gem near the center of Kadıköy.
