We had a wonderful stay at Karen's Pied-a'-terre when we were in town to see a speaker at the University of Chicago. Karen was extremely welcoming and helpful. The location of the apartment was very convenient and we found using the bus easier than driving and parking in other areas of town. The building manager/doorman was also very friendly and extremely helpful.
The fresh delicious popcorn plus water and snacks left for us was wonderful and welcoming and the maps and guidebooks were very helpful. Having read "Devil in the White City," (I'm a huge Eric Larsen fan) it was also neat to learn that we were on the former World's Fair site and see that and another book about it in the apartment.

Karen also called us after we left wondering if a phone charger she had found was our's. Our only regret was that we only got to spend one night due to schedule restrictions on our end. We hope to come back soon!
