The flat is perfectly located to explore Kadiköy or other parts of Istanbul. The room is okay for a solo traveller. Ali just started to rent the room and it requires a bit of touch, like old furniture shall be removed or refurbished. Bathroom and kitchen are for common use (I didn't use the kitchen having so many Turkish food around). I recommend staying at his place, he is a kind host and I believe he will care for the details soon to make the stay perfect. Glad to be his first guest.
