When I was booking, Marc and Jennifer's place was the best choice of all the Airbnbs that were available in Chicago's west side neighborhoods because of several things: (1) a very modern place, (2) own entrance, (3) very safe area, (4) close to major streets with stores/restaurants as well as the L, (5) pet friendly as I was traveling with my dog, (6) great reasonable price.
Once I booked, communicating with Marc was very easy. He was great at accommodating me in regards to the cancellation policy. When I arrived, he messaged me to make sure everything was good and to ask whether I needed anything, such as extra towels, another set of sheets, laundry detergent. The place was very clean and had all the necessities.
In addition, Marc and Jennifer were very nice about small things like dropping mail off at my door if it got delivered to theirs. They responded immediately when I had questions, but I didn't feel dependent on them (in case you are introverted!).
I stayed for 2 weeks. I 100% recommend this place!
