8.4/10 Very Good! (2,094 reviews)
Our room was ok, small but clean. Bed and sheets were very nice. Bathroom was very small. Not a lot of amenities in the room. The beauty of this hotel are the public areas, the lobby and its location in the loop. Nice place, just the rooms were so so. Pretty good food options in the hotel also.
