We contacted Jack the day we arrived Istanbul. He quickly sent responses and was very accommodating. I believe he has been hosting regularly for a while, he was like a professional. Jack's apartment is at a prime location. It is a couple minutes away from the tram stop. It is the best location, if you want to spend time in old Istanbul. The neighborhood, Cihangir, is amazing with lots of cafes, restaurants, bars. The locals are very friendly. Jack's apartment has a balcony with a great view; Bosphorus, Galata Tower, Old Istanbul. There is a park 10 mt down the road, where local people sit, chat, and enjoy the sunset.
