Excellent, stay for four people we were very comfortable and enjoyed the view on the top floor. The location is a few minute's walks down to the water and up to the Galata tower. Close to our favorite restaurant, the Galata Kitchen. The hosts are super kind and communicative, and we were happy that the Taxis could get to the front door. The private lift gives you an actual penthouse experience, and the building has its private hammam and sauna nestled within ancient city walls.
I'm looking forward to coming back!
