I never actually got a chance to meet Juan, but he is very kind, communicative, and helpful, as well as his father. The house is lovely and the neighborhood is really cute and safe. My favorite part was the really large bathtub and rain shower-- definitely a nice bonus! You have full use of the kitchen and fridge, including a built-in filtered water dispenser, so you don't even have to worry about buying a bunch of water bottles for your trip. I would highly recommend staying here, especially if you would like to be near O'Hare Airport or have an event at the Copernicus Center. The metro stop is right nearby, so you can easily travel to downtown if you want. Will definitely be staying here again if I visit in the future!
