Everything was perfect. Besides the very clean and nice and comfortable appartement, the host gives you all the information about the surronding and Istambul itself, you may need. If you have any wishes, or questions you got the answer promptly. Yes, it is on the 4-th floor, but never mind, so the rooftop terrace is very near. :) Bonus: cheap parking lot, right in front of the house. Great! Highly recommended!
