Convenient but dated.
For people visiting the Merchandise Mart there is no more convenient hotel, it's actually connected at the second floor. It also has great views of the Chicago River. That said, the rooms are beginning to show the age of the building and could use an updating. However the people were friendly the convenience is hard to beat. 
Concern: if you drive to Chicago, the fact that this hotel does not have its own parking garage is a concern. I had to park outside in an uncovered adjacent public parking lot and after having my car broken into during my last trip to Chicago, I really worried about the lack of an guarded garage or valet parking. Fortunately I was lucky but this is a concern.
