Great family access to museum campus
We stayed four nights in the hotel with our young children. Because of the cheap rate compared to other family oriented suite type hotels in downtown Chicago, we were able to get two adjoining rooms. Our children enjoyed having their own space, while my wife and I enjoyed the city view at night out of our room. The pool is deep for young kids, as it is a lap pool with no stairs and no depth less than 4 feet, but our kids still enjoyed the pool as an adult was always in the pool with them and there was never anyone trying to swim laps. Both of us adults used the workout room every day and the equipment was in the best shape of any hotel workout area I have seen. It was up to date and well lit with tons of windows. 
The best part of this hotel is its location in relation to the museum area of Chicago. Our whole family walked the 1 mile to Shedd's Aquarium and the Field Museum twice. The one morning it was a long walk as it below freezing with a strong north wind, but we made it in less than 30 minutes. It's a great walk with a few city blocks, then past Soldier Field, and through the park by the Lake. We also drove to Science and Industry, found free street parking, and that was only about 10 minutes away. Also drove to Greek Town which is within 4 miles. Great experience. Parking at the hotel is $30 to park your own car, which in our experience is reasonable in downtown Chicago. There is no free wifi which is why this hotel gets many low ratings, but is a business oriented hotel next to the convention center, and again isn't different from many business hotels in that practice. The only other negative for families is other than the restaurant/lounge at the hotel, there are no immediately accessible dining options. The closest is a McDonald's a few blocks away, and then after that, it's probably 1 mile to others. Worth mentioning too, in contrast with many of the reviews, is that our experience with the staff, both at the counter and concierge, was incredibly positive. Everyone was very nice, helpful, considerate.
