David is a wonderful host, very accommodating, welcoming and attentive. He actually meet me at the train station at 10:30PM (the train with 6 hours late) to accompany me on the bus back to his home in South Chicago. I was comfortable in his home, enjoyed restful nights' sleep and David provided a light breakfast of juice and muffins.
The neighborhood in South Chicago is not the greatest, but I never felt afraid or even uncomfortable walking to and from the bus (2 blocks away) going downtown. David helped me navigate the bus system (CTA schedule and routes) which made travel quite easy.
David is an interesting and easygoing man who I enjoyed meeting and talking with, although we did not have much hangout time since I had meetings both days I was in town.
