Mohammed has a heart of gold and will do anything possible to make your stay a good one. His place is best suited for backpackers and exploration of the great city of Chicago rather than business travelers.
You are better of using the CTA than driving a car to his place - especially in the summer when the Cubs are in town. Since his place is in a great neighborhood - you need a parking permit from the City - or you will get hit with a $75 ticket and parking is tight and expensive.
