Check in was kinda messy, I was told I had no reservation for almost 5min and that's something you don't want to head after a long day traveling.
The place was clean, the beds are comfortable and you may find some cool people as roomies. Wi-fi is good.
Some of the staff were really nice and suggested some "must try" chicago places and gave us some insiders tips.
My biggest complains: There were no working power outlets other than the ones in the bathroom and the housekeeping lady was knocking the door way too loud and early at a monday morning (we still had 2-3 hours to check out).
I'd recommend this place as a 1-2 days stay because of the awesome location.
