Apartment was great. Extremely nice, clean and well provisioned. The rooms were plenty spacious with excess of closet space. Bathroom and kitchen were also extremely nice, and easily accommodated our group. Beds were really comfortable, and with the quiet apartment, we slept great. The location is really good - right next to tons of excellent restaurants, within 5ish minutes of the train, and an easy walk to Wrigley.
David was an impeccable host, and pulled out all of the stops to make us welcome, including moving heaven and earth to get the cable repaired during our visit when the cable box stopped working.
I will absolutely plan to stay here again next time I come to Chicago.
