The hotel has recently opened after a full restoration. Is nicely positioned in the Pera with views of golden horn. I was privileged to have a extra sized corner room with nice views however the only con was the nonstop traffic noise. The staff is very polite and helpful. At the time of booking the hotel was very favorably priced among the other top of the line hotels.
The only disadvantage of Istanbul in general is the nightmare traffic conditions day and night. It needs strong nerve to move around the various sites and restaurants.
