The apartment is great, although it needs to be renovated (cracks on the walls and closets in bad condition). The view worth all the money, you can enjoy Galata tower and the old city sights, the Bosporus and the best sunrises from your window. The location is perfect. Lots of shops and restaurants, easy to reach the subway or tram.
The apartment is on 6th floor in a historical building without elevator. It was slightly hard to pick up the suitcases on the first day, and of course for elderly people it will be hard to do the way every day.
The one thing I didn’t get and it seemed inconvenient for me was a bathroom closet system.
The host was nice and helpful, we had some problems during our stay, but he fixed all of them.
