This was a great place for two families - we had two toddlers, two parents and two grandparents and we all fitted in comfortably.
The area itself has a few things to do if you don't mind walking a few blocks, but it's close to the train station and the garage space means we could easily pop out to the car without having to worry about where we'd get parked when we came back each evening.
All in all it was a great base to explore Chicago and I'd happily recommend it to any other visitors to the city.
