1st if you are staying near O'hare your best bet (if you don't want to take a car) is get on the Blue Line and get off at the Jefferson Park stop, from there take the 92 Foster bus heading west and get off at Clark, Rezas is about a couple blocks north on Clark to Farragut.
If you were staying somewhere downtown you could take the Red Line north (to Howard) and get off at Berwyn, it's maybe about a 5 block walk from there.
There's lots of parking at my house and it's very easy to get to from the airport with minimal congestion, so those are a few options.
If you want you can also download a CTA map.
