I've stayed there a few times, and agree that the location is pretty good for tourism (for business it depends where your business meeting is).
My best was when I booked 10 days in June '94 using UA 50% off coupons, or $100 per night. This was for Gay Games, and I knew the city would be full, so I booked eleven months in advance. In addition, some of the World Cup matches were taking place the same week there, and Hilton was the host hotel for a couple of the foreign delegations.
I'm sure they were kicking themselves for giving away a room so cheaply that week!
