I was thoroughly impressed with this hotel. It's located right by the Monona Terrace Conference and Community Center, and the lakeview we got was amazing. I hope this doesn't demote it or anything, but we were able to get a pretty good deal on Hotwire for a King sized bed for two.
The room was clean and very elegantly decorated. The business center had everything you might need. The pool is quite small, but the fitness center met all of our needs. Only downside is paying for wifi ($10/day). One would expect internet to be complimentary at a Hilton.
In terms of location, it is just amazing. Easy to get to by car, bus, and there's a Madison B-Cycle bike share spot across the street. At night the streets are very quiet, and during the day it's pretty bustling with tourists, business people and visitors to the convention center.
