Roberto and Carlos keep a lovely and clean house, full of amenities and art. If you need anything, they will be prompt to reply and assist in any way they can. I truly recommend staying with them for your visit in Chicago: the house is a half hour from the airport, and another half hour in the opposite direction towards the city centre and activities in Chicago. The neighbourhood is quiet, but has all the little stores and restaurants you could want within a 10 minute walk.
