My favorite thing about the place was the view. Stunning view of the Galata Tower from the main bedroom especially at night. Both balconies also offer a fantastic view of the Galata Tower.
The building is located close to everything you may need; some of the top breakfast spots in the area are within 5 mins walking distance. If you wanna roam around Istanbul, the metro station is a mere 5-min walk as well. The supermarket (Migros Jet) is a literal 2-min walk. There is a cool dude that sets up a small fruit stand right at the entrance of the building every morning.
One surprise detail that's not mentioned anywhere is that the main bathroom with the bathtub has a partial glass ceiling so you get to shower with a view of the sky. The apartment is on the 6th floor so you get a nice work-out in; didn't bother me at all. Since the apartment is the topmost floor, you get easy access to the terrace which also offers a great view of the entire city. There is a table and some chairs there and it was always empty when I stayed so it's basically like a private terrace.
All in all, I would recommend this place to a friend and would definitely stay here again. Special thanks to Irina for great communication!
