It was a pleasant stay for me. Everything was good. They gave me early check-in. Also, because of the long flight, while waiting for the room, I was guided to freshen up in their spa facilities. Just one thing that bothered me was, the walls in every room were so thin that I could hear literally activity from the next room. Also, breakfast was quite good, but I didn't expect only a limited range of buffet, despite them being a 5-star hotel. Overall, I would come back here again if I am visiting Istanbul again.
