We stayed there and my feelings are mixed. It was really expensive compared to alternatives. Was not happy with first (palace) room we had. Business hotel feel inside and the smallest fs room we have been in. Felt cramped with the extra bed for our son. We asked to see alternative rooms. Hotel was full but they were able to move us - and upgrade us - to one of the suites (a 6 category upgrade i believe :-) next day which obviously made us enjoy the room fully for the rest of the stay. View of bosphorus wonderful but since there was no balcony or terrasse, it was less perfect for us. Loved the pool. Great coming back there after sightseeing to relax. Service mainly good but not perfect. Food choice limited but there were loads of other places to go for that
of course. Will write a full report when we get back.
