Ali was an excellent host. He is a really friendly guy who was always available to help us during our stay.
His apartment is super nice with a big living space and kitchen, and a wonderful view of the Bosphorus (the same view as the 5-star hotel across the road. It was incredible to watch the beautiful sunsets on the Istanbul skyline.
The only small thing was that the flat is on the top floor with no elevator. Personally, I enjoyed the exercise of climbing the many steps, but for some this might be more problematic. Ali was a gentleman though, and helped us with our many bags which made life a lot easier!
