Enjoyed a weekend in Chicago and stayed at the Radisson Blu Aqua Hotel. From check-in to check-out, the experience was excellent.
This hotel is an easy walk to many of the Chicago sites. I tend to do a lot of walking while on vacation, and I will say Chicago is a multilayered city and you need to be aware of what is considered "street level". Google Maps gave me a little trouble with walking directions. That is a very minor item, and those familiar with the city will have no problem.
I enjoyed a couple cocktails at the bar, but did not eat in the restaurant. The outdoor pool and the work out area were very nice and easy to use.
I would certainly recommend this hotel for anyone spending a weekend or so seeing the sites in Chicago.
