I was admittedly skeptical upon booking the flat as such a low price for such a great view and location couldn't be true...but this place is spectacular. The room is very nicely sized for 2 quests; the bed is quite comfortable; the bathroom modern and nicely lit...and the view is just amazing. A true panoramic view of the Bosphorus and Topkapi, the Blue Mosque, etc... and you see it from sunrise to sunset. The south facing floor to ceiling windows slide open and the west facing bamk of windows open to provide a nice cross breeze (but it's nice there's an ac unit as the sun heats up this top-floor room).
And Ali is a wonderful host. He made check-in rather quick and was very available when needed. (The elevator didn't work one morning and upon telling Ali this he hopped on the phone and we arrived back to the flat after lunch to a working lift.)
And the location is fantastic. There are several nearby restaurants and cafes and attractions...and it's a great jumping-off point for those who like to walk. That said, it's difficult to find if you don't know the area, but once there it's easy to arrive at. Also, it is a place for walkers as it rests at the bottom of a hill on a cobble-stone street.
I cannot recommend this location enough and I hope to be fortunate enough to return.
