The hotel is nice and quite cozy. However, there's nothing exceptional in it unless you count a terrace which is comfy but most of the hotels have it in that area.
Be prepared to pay extra if you want to get a room on the top floor or with the sea view. Breakfast is 8 to 10 am and that's not exactly the time I am used to wake up at, so I had it only twice - it's a traditional Turkish breakfast plus extra crepe/omelet. The hotel is located really close to historical area in Sultanahmet district. But once you want to go somewhere be prepared to be called several times per minute to eat at some Cafe - there's a whole street of it and Turks do not understand rejects at all.
In general, the stay did cost its money but I guess you may find more interesting places to stay at for the comparable price.
