Knowing Jon and Viviana personally it's hard to be unbiased... but I'll try. They really love to host people and make them comfortable. We had great conversation in the backyard. If I had any issue or question, they responded right away.
Check in was very straightforward. The house is in a quiet, really nice neighborhood close to Jewel, some local stores, a park and public transit. Getting to downtown and O'Hare is super simple.
Highly recommended!
