Fatih's studio is the perfect place for exploring Istanbul. It's located in the heart of Galata, where you can do excellent shopping and eating. Even though, the place is in a quiet area. From Galata you can reach the Sultanahmed area easily by tram or on foot, or take a ferry to the Asian side.
As a host, Fatih is very kind and willing to share his tips and advice (where to eat, how to get to the airport etc). Recommended!
