Enjoyed staying here - comfortable, quiet (save the 6am call to prayer from somewhere nearby) rooms on the top floor (mine had a great balcony too), and very friendly helpful staff. The location near Galata tower is good and there's a good amount of shops, restaurants, cafes etc nearby. The walk up to the hotel from where the water is is pretty steep however, so take that into account if you are lacking in fitness/mobility.
