Lots of people complain that having a crashpad in Chicago sucks, and if they're located off of the Cumberland stop, they're generally correct.

Take some effort to find a crashpad slightly deeper in on the Blue Line; Jefferson Park, Logan Square, California. So that way if you have to sit in a crashpad at least you're doing so in a vibrant neighborhood with plenty of activities.

Also, get yourself a Ventra card. Chicago has one of the best public transportation systems in the country; the Ventra card will make accessing it that much easier.
