We stayed at several different airbnbs around Istanbul and know what's available - this top floor penthouse was easily the best value. We absolutely loved it and stayed for 18 days. It's in a great location not at the loud center but less than five minutes walk to different points of interest. You can see the Galata Tower day and night from the windows. The kitchen is well equipped with everything you need including the electro grill and the dishwasher. The terrace is incredible, I did the morning yoga there and loved it.
The 360° view is worth climbing 5 floors up. If you are about to book this place but for some reason are hesitating, don't. You will not regret staying here. We will definitely come back.
