Isik's apartment is in an excellent location near Taksim square. We took a taxi in from Ataturk airport, and Isik met us near the apartment to take us up. Is it also close to the Havatas shuttle, which was super convenient, as well as Istiklal Caddesi and lots of transportation (or walking!) options. The apartment itself was super clean, with all the basics: hair dryer, sheets, towels, drinking water, wifi, etc. The apartment is also close to restaurants and shops to buy items such as coffee or snacks. Isik was responsive to texts and very helpful in general. I would highly recommend staying at Isik's apartment while visiting the beautiful city of Istanbul.
