It's also across the street from the Westin River North, which IMO (along with the Autograph) has the best location in River North due to close proximity to Blue, Red, and Brown lines.
Had a few stays at this property a few years ago...had positive impressions overall. My only Autograph stay to date. It was head and shoulders better IMO than the Marriott Michigan Ave, which felt like a factory w/tiny boring rooms.
