After a 6 million renovation, this luxury hotel has set up shop in famed Chicago architect Daniel Burnham's former Commercial Bank Building. The 610-room hotel focuses on modern luxury with crisp and sophisticated rooms set with bright, warm colors and amenities like an indoor pool and a spa complete with Turkish baths. Although located in the heart of the Loop's financial district, there's hardly a reason to leave, especially when you factor in Todd Stein's contemporary Italian restaurant, The Florentine, on the second floor.
