Alex and Laura are perfect hosts. They were easily available if we needed them, but not intrusive in any way. They met us upon our arrival and gave us a brief informative tour of the place. Alex checked in via message a few times, and even sent us a coupon for a local pub.
The apartment itself was spotless and comfortable, with air-conditioning and plenty of space. It's a five minute walk to the Blue Line train, so you can get anywhere, fast.
We will try to stay here any time we are in Chicago.
