The Concierge at Fairmont Chicago Millennium Park

"This “elegant” conference hotel is “close to everything yet quieter than staying on Michigan Avenue”, and has “spacious”, clean-lined rooms and suites with “gorgeous” marble bathrooms (higher-floor rooms have views of the lake); the "concierge service is extraordinary”, offering help with ticketing and babysitting services, and other bonuses are a luxury spa, 24-hour fitness studio and “fabulous food” at the on-site sushi restaurant"

"Close to the Magnificent Mile and the north end of Millennium Park, this Loop area hotel is a swank sleep with almost 700 guestrooms, an 11,000-square-foot spa and an exclusive 15th-floor concierge level"
