I stayed at Alican's apartment for 2 night with my mom and my 2.5 year old son. I chose his apartment because of its location and its terrace with a view of the Bosporus bridge. The unit itself is a bit rundown but it was clean and had everything we needed. Alican is a great host and replied my emails promptly.
Pros: Large terrace with unbeatable view and comfy seating, steps away from Bosporus sea side, Ortakoy shops and restaurants.
Cons: No elevator (apartment on top 5th floor)
