Time Out says
If you're in town for an event at the Convention Center, Hilton Austin will likely serve as your homebase. The massive lobby houses a Starbucks, restaurant (Cannon & Belle) and lounge area that serves as a meeting spot for business conferences and family gatherings. Take advantage of the in-house spa (hello, mani-pedi), the health center and the outdoor pool and hot tub. But don't get too comfortable—there's plenty to do around the Hilton's immediate area, as it's situated within walking distance of Rainey Street, East 6th Street and the rest of downtown Austin.
