I had never stayed in a hostel situation before and was a little apprehensive. As it turned out, I really enjoyed meeting the other guests and my stay was much more enjoyable as a result. In many ways it's more fun than a standard hotel would be. The rooms are not large but that's offset by ample common areas including a large-screen TV in the basement common room. Cleanliness is good throughout and the availability of multiple full kitchens is a feature you wouldn't find almost anywhere else. I'd definitely return.
As a final note, be aware that this property literally is in the shadow of Wrigley Field, along with the surrounding sports bar scene. On game days, the neighborhood will be - well, just use your imagination. If being near Wrigley is what you're looking for, there couldn't be anything closer without buying a ticket.
