We were in what was described as a Mega room with 2 doubles that seemed to be at least twice this size of this picture. The room chart seemed to show all the rooms on the floor relatively the same size (except for the corners)

On the 16th floor (our room was across from the elevators with the windows facing south), the ceiling was quite high which made the room seem even huger for NYC standards.

Service was outstanding! Location was the best of all the spg properties we've visited.
