My wife and I have just returned from a 5 night stay at the Waldorf Astoria Chicago. Good central location downtown and with easy access to the 'L'. The rooms and in particular the bathrooms are exceptional. However the real highlight of this hotel is the staff. They cannot do enough to make you feel welcome. All staff including the Guest Relations Director introduced themselves. I have stayed in some excellent hotels in the USA but the Waldorf Astoria Chicago is in a class of its own.
