Mustafa's place is a must stay if you're looking for something in Old Istanbul. It ticked all the boxes for me and more, with super location, amazing hospitality and communication, and more. He went above and beyond and the space was super clean and neat. My only wish is I could stayed longer. I will definitely book with him on my return. He has many places so be sure to ask if this one is booked. The place even had some lovely and bright and spacious common areas, including a kitchen, rooftop balcony and lounge area and a working area/living space. Hands down thee best place to stay in Old Istanbul with the best host as well.
