We stayed for six nights. The location of the hotel was captivating. We did not lose it, in a few minutes tram T1 which goes all over the center and towards Dolmabahce. There are breakfasts, the same, but generally delicious. The rooms are clean, but wet cleaning has not been done once in a week. We changed the towels. If something is needed, they give it out. In general, the staff is friendly. I would stay there again.
Everything, in general, is fine. And the room, and the location, and transport to different places. The food, however, is not a buffet, but what will be brought on a tray in the Turkish style. You won't be hungry, but you won't overeat either.
