Tim was a very accommodating and flexible host. He graciously stayed up to receive us at midnight when we encountered significant flight delays. He patiently gave us detailed recommendations for places to have dinner that night. He provided a light breakfast for us the next morning. He was kind enough to let us keep our luggage with him while we toured Chicago the day we were supposed to check out.
He is very prompt in responding.
His place is located in a quiet suburb of Chicago.
