The hosts, Ilyas and Acelya are extremely nice and responsive, we are happy to have met them!
The apartment is spacious, you have all you need for a stay, may be except for a microwave. The location is also very good - all shops are nearby, there is a nice park where you can go with children just 7 min walk. The place is not far from Taksim as well, takes about 20 min on foot.
I would recommend the place.
