I had an amazing week in Chicago.
The house is one stop away from the convention center at Cermack McCormick Place, which makes it an optimal choice at a fair price for a conference week. The neighborhood is sketchy, but the street of the house is okay - just take Uber at night.
The interaction with the host was great. He was super responsive, helpful and attentive towards my needs in a bunch of situations. Easy check-in/check-out.
