Karen is an absolutely lovely host, extremely attentive to your needs with a lot of respect for your privacy, and her apartment is a great place to stay. Lots of light, warm, homy but not crowded at all, just perfect. I stayed with her for a congress in McCormick and it's an ideal location for that. Direct bus (#3) picking you up right in front of the apartment and leaving you in McCormick in ~10min or all the way downtown for your night events. I would love to stay there again in my next Chicago trip!
