New Year's Eve stay for a concert at Time Warner Arena (5 - 10 min walk).  Other than the inflated holiday price, I was very happy.  Beautiful and clean common areas, clean, nicely appointed room (21st floor), staff was super friendly, and hotel is connected by interior walkway to a full, new-looking YMCA you can use just by signing in with your room # and DOB (this ain't your typical hotel gym).  The location was perfect for a short stay to attend an event in center city.  Everything you need is within walking distance.
