This has to be the best Five-Star Hotel in Chicago. The Park Hyatt is just the right size, about 200 rooms which gives the staff the ability to personalize the service. The rooms are the largest in town and very modern. Great views looking out on the Water Tower and Michigan Avenue. Nomi bar and restaurant are first class and the spa, workout room and pool are a delight. Have stayed at the Park Hyatt probably five times over the past eight years and it just keeps getting better.
