We had a great time in Istanbul, especially staying at Ozy's apartment. While he was unfortunately not able to meet us upon arrival, his friend was able to show us the place and answered all of our questions. The apartment was as listed here and located right in a great area of the city, not far from Taksim Square. He does live on the 5th floor of a building with no elevator which may be an issue for some, but he did warn us beforehand and it was never an issue for us, as we were out sightseeing for most of the days we were there. Overall, it was a great experience and we are very thankful to Ozy for sharing his apartment with us. Would recommend to others.
