good. would definitely recommend to others. Located in a small street in Taksim, a bit far but less 15mins walk from Taksim metro station. It's on residential area so a bit quiet at night. Well-equipped flat, stable and fast wifi, kitchenware, kettle, microwave oven, washing machine in basement, but no oven and bodywash. Staff were helpful and nice. Highly appreciated that there was a booklet providing the travellers some very useful tips for the flat and knowing of Istanbul.
Enjoy my stay there!
