I am planning to take the L train to the hotel from O'Hare airport. What train do I take and what stop is closest to the North Michigan Ave. location? Thanks.

Sorry I can't help you with this one, we drove to Chicago. The Hotel staff were very friendly and helpful. Just give them a call or drop an email asking for your answers. They will gladly help you out.

Chicago Ave

That I can't really tell you me and my wife drove
