As expected based on existing reviews: a comfy apartment very close to Chicago 'L' metro station (Irving Park) and bus hub. With the 'L' blue line you can go directly to/from O'Hare airport or to the city center/pier areas (the Chicago 'L' loop).
At the apartment: fully-equipped kitchen, so breakfast or dinner is not a problem (not mentioning the coffee machine and a big jar of coffee waiting for you). There is also a shared washing machine and dryer in the building, for $1 and $1.25 respectively (have coins prepared).
Thanks!
