Had a pleasent stay. Host was always responsive. From here all the main places are around 4 to 6 km approx. There is also a cute street nearby this place. Must explore it. You can get taxi right in front of the building and go to all the popular places like taksim square, Galata tower, Grand bazaar/spice bazaar, Hagia sophia etc. There are lot of yatch cruises in front of the apartment. Best place to stay.
