Don't know of any particular places available, but off the blue line (train) from O'Hare a lot of people stay at either Cumberland or Jefferson Park which are both close to the airport. If you want some more action, try finding a place closer to downtown around the Damen or Division stops.
The "Concrete Jungle" area to the east of the Cumberland Ave L stop is a big haven for crash pads. Just walk around there long enough and you'll see someone in uniform heading for the L stop. Ask them about their crash pad and if they know anyplace looking for someone.
