It's hotel-like with Airbnb prices :-)
Prior to flying to Istanbul Güner sent a .ppt file giving useful details on how to reach the location, and advices on making your stay easier, cost efficient, with recommendations on what to see, where to eat and where to buy. Very, very useful.
I highly recommend staying at Istanberry Dream Flats #07!
FYI: Güner manages several locations and flats in Istanbul.
