not far away from blue mosque , hagia sophia , grand bazar .
Mr Rifaat are very responsive host .
But to getting to the place i recommended taxi or minibus( private ) because the new Ataturk Airport only provide bus to the area blue mosque ( maybe ) .
the cost of the minibus/taxi very expensive from the airport.
so I recommended you can get minibus/taxi at arrival floor , then someone will approach you to offer their transport. Please be carefully, because some of them will take advantages of you by offering very expensive rate up to 1000 or more Turkish Lira .
However Mr Rifaat are very helpful. He help me to carry our heavy luggage & help us to get minibus/taxi back to the airport.
you need climb something like high road/most probably bit mountain ( i think to get to blue mosque etc ).
If you carry a baby stroller, it will be challenging for you.
most of all recommended place to stay
