We spent one week in mid-april in Fatih's studio and had a great stay. The location is just amazing! Close to the Galata tower, a minute from Istiklal Caddesi, and with easy access to the tramway. You can also easily walk to the Galata bridge and make your way to the blue Mosque, Aya Sofya, etc. The studio was very clean, but seemed smaller than what we had seen on the pictures, especially for the bathroom which was very small. But the kitchen was well equipped and we were happy to be able to cook a little bit, even if Istanbul's food is just amazing! Bring some earplugs and a mask, it can be noisy at night and there is a lot of light coming through the windows. Overall we had a great stay, and we really recommend staying there. Fatih was a great host!
