Covnenient location, classic hotel, but not worth it
I got this room using Hilton points so it was worth it in that respect, but if I had to pay the $400+ they were looking for a room on the same night, I would not have been to pleased. It wouldn't be my first choice in Chicago as there are several other nicer hotels for the same money. I was stuck here due to the Chicago Marathon going on the same weekend. Such is life.
As for the hotel, it is old and classic. It's great looking in a great location with an impressive lobby. So they get points for that. The negatives: long check-in lines. There are many rooms in this hotel but they don't have the check-in staff to keep up with it. Also the walls are paper thin. I had a terrible night's sleep here due to that. You could hear doors slamming all night long along with rude people (not the hotel's fault) shouting all night in the hallways as they come home drunk. While the hotel cannot control its people, they can have better doors/walls something. You can hear someone sneeze next door and for some reason our toilet would run for a second every 5 minutes or so. 
The rooms are small, but that is to be expected. If you're one who likes to enjoy their hotel while on vacation and spread out in the room, I wouldn't stay here. If you're here for a night and want to be in a hotel that is very convenient and right outside a red line subway stop, then this is it. 
I wouldn't stay here again unless I had to, long story short.
