The view from Cansu's place is truly amazing - large windows in each room with a full panoramic view of the Bhosphorus. The bedroom looks over the Bhosphorus and Ortakoy bridge, and the living room/kitchen look over the Bhosphorus to the south. However, to reach Cansu's apartment, one must hike up a hill and then climb 4 flights of stairs. There is no elevator in the building. If you are strong, this climb is certainly worth the breath-taking view.
The apartment is spacious and clean. The guest bedroom is large, with a comfortable bed. In the bedroom are just the bed, a night-table and a tiny table and chair. There is no dresser or wardrobe to store your things. The bathroom is also large and attractive.
Cansu smokes throughout the apartment, and you can smell smoke in all the rooms, so I recommend her place to smokers.
There was no internet in my room, and only weak and sporadic internet in the living room during my stay. You might want to inquire with Cansu if she has fixed this problem.
