David's place is a real gem. The accommodation is a 15min brisk walk from the blue line metro, which makes it ideally located for exploring Chicago and accessing the airport. Of all the places I have stayed this was the cleanest - absolutely spotless. The bed was comfortable and the downstairs rooms spacious. Private access means that you can come and go at your leisure.
Communications were easy and David proactively reached out on a number of occasions to ensure that my journey was panning out as planned.
I wholly recommend David as a host and would definitely try and stay again if I am ever Chicago bound.
