We've spent almost a month in this beautiful appartment. Place was really clean, warm and furnished with all brand new facilities and furnitures of famous manufacturers.
Location is close to metro station and has good infrastructure - supermarkets and pharmacy, also few big shopping malls and outlet mall nearby.
Host was very kind and helpfull - arranged very good internet connection during our stay. Appartment complex has also free gym and nice sauna with traditional hammam.
It is definitely the best appartment to rent in Istanbul
