This is a really nice unit for your visit to Chicago. The unit was very clean and spacious. The beds were very comfortable with plenty of pillows. The layout of the unit is convenient for separate couples to stay, as the bedrooms are on the opposite ends of the common space. Huge living/dining room and plenty of space in the kitchen if you care to cook (we didn't!). Parking is super convenient. We paid $15/night to be right next to the building. Not much to see right in the area but only three blocks to a train station or bus stop.
My only complaint is that considering the unit advertises for up to seven people, it could use more seating in the common area. Only four dining chairs at a small table, and one couch with two chairs in the living room.
Host was great at communication. Our concerns were addressed promptly (no carafe for the coffee machine was fixed by a brand new coffee machine the next day). I recommend this unit for your small group staying in Chicago. Not super fancy but everything you need.
