I stayed for one month.
The flat is very good clean and almost have all your needs.
The area is middle crouded the street is not noisy at all. The nearby streets in 200 to 1000 meter have different restaurants shops cafes.
The public transportation is excellent. The metrbus is 200 meter.
In 3 km the Marmaray speed metro.
Overall recommended. You are in good location in Istanbul to reach your target places.
