Lovely apartment right in the centre - 5 min walk from the bean! We had a lovely time exploring Chicago and went on foot everywhere. If you are coming from the airport the blue line is likely to be faster and cheaper than a taxi but can be a bit tricky if you have lots of luggage.
The door staff are really nice and welcoming. The flat is small but sufficient for 4 people, there are great views from the flat and roof Terrace. Beds are comfy and bathrooms are spacious. We only had breakfast at the flat but the kitchen had everything we needed and make coffee. We drank the water from the tap which seemed ok.
The pool, gym and terrace are a bit run down but usable,. My son went to the gym every morning and had it mostly to himself, the pool (accessed by crossing over to another building on 6 floor) was cold but seemed clean and had lovely seating around it although we did not sit for long as it was in the shade when we went. The roof terrace has seen better days but if you just want to see the view and chill for a bit it is fine.
