We were five students who booked a room at the Grant Park. Overall, we had a good experience.
Pluses: Clean, helpful staff, convenient location on the edge of the Loop, not far from the McCormick Convention Center and close to the El.
Minuses: Make sure your suite really has a fold-out couch. Ours did not, and we weren't allowed a roll-a-bed (Chicago law?), so one of us bunked on the couch. The bathroom did not have a sink separate from the toilet/shower, which is a problem when you have five women in a room.
Warning: The restaurant next door makes hideously awful cocktails so be forewarned!
The price was excellent because we booked well in advance, so overall, I recommend it.

We were quite high up so the view out of the window was good
Liked Chicago very much loved millenium park.
Parking in the surrounding area was poor. Understand the coach driver had to move the coach in the middle of the night.

This hotel was an excellent choice for comfortable, affordable lodging in the downtown Chicago area. It is located right across the street from the Field Museum and Aquarium. The room was not plush but certainly pleasant. Best of all, the customer service by all front desk personnel was outstanding. Very helpful with advice on nearby restaurants and transportation options for getting around town. I would return to this hotel in a heartbeat.

We were looking for accommodation in down town Chicago that was clean but was in our price range. This hotel surpassed our expectations, actually working out less expensive than we were originally quoted. Whilst the decor may be some what dated, it provided the service required.
