The Congress Plaza Hotel is a great place to stay in downtown Chicago. The rooms are clean and well stocked. The high ceilings make an ordinary sized room feel much bigger than it is. And the views over Lake Michigan were spectacular through the large windows, especially at sunrise. And if early mornings aren't your thing, the blackout curtains will make the room dark even in the harshest or early light.
The hotel was close to everything we came to town to do.
Overall it was a great place to stay. We highly recommend it.
