Spent three nights recently in a Governors Club room - while the lounge was a nice perk (even had eggs in the am, so it is much more than a continental option), must agree with other reviewers about loud (and iffy) AC units and my personal pet peeve, lumpy pillows.
No complaints on the service in anyway and overall a great location if you are staying in Madison. Visit the farmers market on Weds and Sat if you are around.
