This is a great place if you're out doing activities all day and primarily need a place all to yourself to sleep/rest. You won't be able to cook full meals, but there is a microwave and kettle, and plenty of restaurants/grocery stores in the neighbourhood. Close to public transit also.
Fahri was very communicative and flexible with my check-in and check-out times and even offered to arrange transport for me. I was just staying one night in Istanbul for a bus connection and he really made it easy for me because my bus departed late in the evening.
The place is nothing special but it's clean and safe and you can't beat the price.
