Good location, alright hotel
Well the hotel location is good, it is one block away from the Magnificent Mile in a quieter less chaotic but very safe location. The only drawback is that it is about a 15min walk away from the nearest L station, which i thought the closest was Grand/State Red Line. Not a bad walk though, felt safe even late at night when everything was closed. Its only a couple blocks from Navy Pier and there was a free shuttle too, which we didn't use.
We stayed in a King room on the 7th floor. It was nice, still had a tube TV though, and everything seemed just a little bit dated in the room. nothing that particularly stood out as amazing or something to talk about later. not totally what i would've expected in a Hyatt. It was nice though, and clean. there was no free wifi or even wired internet, it all was a charge, which was an inconvenience. 
I would recommend this hotel to someone on business or families. Since its in a quieter and safter neighborhood. I would not recommend going with friends, its not a good place for party goers since you may want somewhere more centralized to the loop or at least closer to mass transit.
