This is a shared room stay and you are gonna meet plenty of travelers or young people just moved to the city to find a job and stay in Chicago.
to keep a big shared space like this managed for all, there are a lot of rules everybody has to follow. so make sure you red that part. if u r ok staying around others and don't mind regulation then you can save a whole bunch of money. comparing with my other options I saved 400 bucks in two weeks here.
