It is comfortable and clean apartment. Also good location, near to the 2 big malls, 2 lines of metro. Also there is gym and swimming pool for free. Good collection of dishes, towels, spices and salt, dishwasher, shampoo, toothpaste. It will be good place to stay in Istanbul, even if we travel lightly. It not so close to historical centre, but if you have active life stile it is not an issue because of rich transport allowance (especially with metro).
