Outstanding stay from beginning to end. The staff are, without exaggeration, the most helpful I've experienced at any hotel, ever. I wish I could remember his name to praise him as he deserves, but the gentleman who was working when I checked didn't just check me in. He walked me over to the couch, the other staff brought a welcome drink and Turkish Delight. He asked what brought me there and when I said tourism, he brought up several sites to see how much I know about Istanbul,pulled out a map, marked where they, discussed walking times and distances, and a suggested itinerary. If we requested something for the room like fresh towels they were brought up quickly. They were helpful with a spa, restaurant reservations, airport transportation. The room itself was the nicest I've stayed at in Istanbul but the staff alone is good reason to stay here.
