As a solo traveler I enjoyed my stay in this apartment especially in the beautiful garden. I had a great time in Istanbul and Tolga is a lovely host - very helpful, friendly and happy to have chat.
The location is perfect, you can walk to many places in Şişli/Nişantaşı ( taxies also can be found easily in this area) . The apartment is neat, clean and suitable for couples. Check in/Check out was nice and easy.
