Saint Kates is upscale and usually out of our price range, but when we "can" get a price break it is our choice. Great location, rooms are very nice, quiet, clean and comfortable.
We did only have one washcloth, which was odd because we had plenty of towels, but that was very minor.
Saint Kates is located well, and is an easy walk to anything in the downtown area. We were going to the nearby Pabst Theater, but almost all the music venues were close from there.
They have an excellent bar area but expect it pretty crowded on a Friday night. Great dining options (although we opted for other arrangements), and a staff that works with you right away if there are issues.
All in all, Saint Kates (if you can afford it) is one of the best for downtown Milwaukee.
