We had a really great stay at Koray's place and can highly recommend it. The apartment was so lovely we barely wanted to leave it - it is just as it is in the pictures. The view from the balcony is simply stunning and was just so nice to sit out and watch the boats go by. Also the apartment is in a really nice location, with lots of little restaurants and cafes nearby. Would definitely stay here again if we are back in Istanbul. Thanks!
