Olcay's place is great value in the heart of Istanbul. Istiklal street, the main pedestrian thoroughfare, is literally a 2-minute walk from his building, and the neighborhood of Cihangir contains a lot of trendy cafes and eateries. I should also say that Olcay was very quick to respond to any questions I had during my stay. Even though it's very close to nightlife and public transportation, the apartment itself is very quiet. Overall I would recommend it as a good option to anyone looking for a "home base" from which to go out and explore the European side of the city.
