The apartment was great for what I needed when I attended a conference at the McCormick Center. The walk to the McCormick Center was much shorter than the walk through the McCormick Center to get to the meeting rooms; the McCormick Center is enormous. So, it was easy to come and go when I had a few spare hours during the day.
There was some building work in progress in the foyer of the apartment building, but it did not cause any problems. The laundry is behind the foyer and requires a pile of quarters.
There were no grocery stores, supermarkets or restaurants within an easy walk other than a McDonalds, so I did not cook for myself (which I usually do).
Unlike many places, I slept really well in Christopher's apartment. I don't know what made the difference, perhaps the combination of comfortable bed and dark curtains.
If that conference cycles back to Chicago and the McCormick Center, then I would be happy to stay in Christopher's apartment again.
