I stayed with Mary the night before my Step 2 CS exam! Her place is so ideal for this--4 minute drive to the testing facility, lots of street parking, close to O'Hare/public transit if you're not driving in. Plus, the bed is SUPER comfy, Mary is friendly but will give you your space to study/unwind, and having breakfast provided was great. I arrived around dinnertime Tuesday and walked around the neighborhood, which is a quiet residential area with a great, big park three blocks from the house. The room and house have everything you need. It was very clean, I had a desk to study at in the bedroom, and enjoyed fresh fruit, a bagel, and coffee before the test! And seriously--I slept like a dream. There are planes going overhead somewhat regularly but they didn't keep me up at all and aren't too noticeable inside the house. I'd definitely recommend staying here for travelers and CS takers!
