Hanife's place is one of the best you can find in Istanbul when taking the price/benefits ration into consideration. I had to rent it mainly for my mother to stay for more than a month, but I also stayed there and had no issues whatsoever. Hanife treated my mother like her family and was extremely helpful throughout the trip, and was always very kind, polite and hospitable.
There are multiple shops and restaurants less than a minute away from the house, along with a park and shopping street a few minutes away. The house was sparkling clean, had all the amenities mentioned and we didn't face any issue. A previous guest had mentioned some leakage during rain, but that wasn't applicable any more as it rained quite a few times when we were there and we didn't have any dripping roof issue. The apartment is also at walking distance from Forum Istanbul and a Hava Ist (Airport shuttle) stop. I can't recommend her place enough, and reiterate how wonderful of a host she is.
