I was in Chicago to watch the ITU World Champs. Nate's place was out of the city, but a 3-4 minute walk to the nearest El Train station that takes you straight into the CBD. The neighbourhood is lovely, quiet and friendly. It was really easy to get into the apartment, and leave on the last day. Nate makes you feel very welcome, and the apartment is lovely. I had it just for myself, but it would easily fit more people comfortably.
