We stayed at the Sheraton by Navy Pier the first weekend of November and were very pleased with the accommodations and the service. We were upgraded to club level rooms and stayed in 3114 and 3115 adjoining. The view from both rooms was spectacular (as you can tell from the picture attached). They also left a plate of cookies and treats in the kids room upon check-in which made us all feel very special. The hotel is central to both Navy Pier and Michigan Ave. so we walked, trolleyed, and cabbed all around the area. We ate the breakfast buffet both mornings and thought it was pretty good. The eggs were a little runny, but they happily made a different batch for us at the omelet station. Our six year old ate free and our two eleven year olds were $14 (instead of the adult $20) The rooms were clean, the concierge & reception staff were both friendly and helpful...we will definitely visit this Sheraton again when we're in Chicago next time.

Output:
positive
