I stayed there the other week for one night and yes it is very 5*. Fortunately for me it was a free night stay. I didn't have to open my wallet so the moths couldn't escape.
Personally I wouldn't pay the prices asked for but if you're into 5* luxury and money is no option then yes it is still one of the places to stay. I actually prefer the look and location of the Hilton although I have no idea if it gets good reviews.
