Stayed in a queen-size bed room. Location is absolutely excellent, wonderful proximity to great restaurants, Oak street/Ohio St beach, Magnificent Mile shops, Millenium Park, Lincoln Park, Garfield Conservatory, Buckingham Fountain, Chicago Art Institute, etc. Definitely a super convenient place to stay. Hotel also has a nice bar/lounge on the first floor that was fairly packed during the nights we were there (4th of July weekend), and is close to some other nightlife.
Staff was really kind, only thing I didn't love was the $30 check-in fee to check in before 3:00pm. It was very kind of them to hold onto our luggage after we checked out and before we checked in however. I liked that towels/room clean was on request, so it wasn't like we were wasting a ton of resources and having unnecessary cleaning done.
One negative was the room was pretty small, but this is probably par for the course in downtown Chicago at the price point we were at. The bathroom was also pretty small. The heating didn't seem to really work, it was pretty cold in our room and we weren't really able to fix that. Finally, it was a bit difficult to stay hydrated b/c the water fountain is in the basement (room can be as high as the 14th floor) so make sure to bring a 1 L water bottle and fill that up twice daily to get enough hydration.
