The location of the apartment is fantastic. All the historical sites in Sultanahmet are a 5-10 min walk away. Saban was very helpful before the trip and even helped some of my other friends find a place to stay nearby. The room would be cleaned everyday by a maid and towels + floor mat would also be changed.
If you plan to use this apartment as a base point to explore the splendor of Istanbul it is definitely recommended. However if you intend to pamper yourself with some luxury then a hotel would be more suitable.
