Fantastic stay!
My husband and I stayed at the Residence Inn Chicago River North for 2 nights in Feb. while I had a business meeting. Self parking (at first confusing) turned out to be easy but costly-$40/night for in and out service. Check in was fast, and everyone from the door men and front desk to breakfast attendants were very friendly. We stayed in the King corner suite which was very big and clean. I love having a full size fridg with ice maker, plates, all kinds of glassware and utensils at our disposal. Except for the included breakfast we ate our dinners out and reheated leftovers for lunch. There is a full size coffee maker - if you're staying an extended time and love your coffee bring your favorite brand with filters. No tub but the shower is huge and spotless.
Harry Caray's steakhouse is across the street and the House of Blues is just down the block. If you are looking at hotel/suites in downtown Chicago the Springhill Suites is actually in the same building (FYI).
The pool looked nice but was loaded with kids on Sat night so didn't go in.. 
I booked this hotel 6 weeks in advance of our trip and kept checking prices. I ended up saving $100 when I checked online the night before leaving home and the price had dropped so I called the toll free number and they happily gave me the lower price.
Great place to stay in Chicago I highly recommend it.
