Just book this place now. Not only is it super cute & super clean, the location is great!
It's in a very "Brooklyn-ish" part of Chicago called Logan Square. We used public transportation for our trip, and it was very convenient to catch the 56 bus a minute from the entrance and connect to the Blue Line which takes you straight to O'Hare.
If you are comfortable with taking public trans (its safe and clean in this city I will say), then it's definitely the way to go. For $20, we got a 3 day pass that got us everywhere. We did not spend any other money on transportation, and we saw every part of the city.
Even though it's self check in, the hosts are very warm and welcoming in their messages and in the ambiance they've created in the room. The place feels like home. The kitchen is well stocked if you actually want to cook something, the bed is EXTREMELY comfortable, and the bathroom is spacious.
There is a private deck just across the hall if you need a place to smoke or watch the sunset.
