This place is in the heart of Taksim just 2blocks from the Taksim square, everything is near you, transportation, groceries , shopping, and the metro
Also the airport bus is very close as a way of transportation from, and to new Istanbul airport which make things super duper easy .the host was nice, with quick response, and the apartment is as advertised( the only down part is being in the 4th floor with no elevator) .but it was manageable. I recommend this place .
