Awesome hotel, an island of peace and calm and first class treatment in a sea of chaos at O'Hare airport. Staff, restaurant, services--worth every penny. Early departure? Stay here the night before. We did. Calmly woke up and walked to the terminal thru the underground walkways. Truly pleasant and memorable stay.
