Let me start with the tiny drawback which comes with the rooftop as one can imagine :) the apartment is on the fourth floor and there is no elevator. So if you have problems with stairs, this might not be the best place for you. Other than that, I enjoyed my stay very much. I love Kadikoy/Moda neighborhood and the place is in the hearth of Moda. I could not enjoy the rooftop because the waether was pretty cold but it looked quite nice. You can easily access the restaurants, cafes, supermarkets and also ferry terminal, metro station etc.
You would also have full privacy since it is an independent apartment. It was very easy to communicate and easy/pleasant check in. I was able to do an early check in since the place was ready. It has everything you need, a small kitchen with supplies, even though I did not use them since there are enough restaurant around with good food :), comforable double bed, pleasant shower.
Overall it was a very pleasant stay
