I grew up in Milwaukee and spent a lot of time downtown when I was going to college. I remember the Ambassador Hotel's reputation back then and must say that they did fantastic with the renovations and improvements that were made. You feel like you stepped back into time when you walk into the lobby. The hotel itself is beautiful and the location is very convenient.
Overall, the staff was great, the bar, room we stayed in, and restaurant were all very nice.
I'd stay there again when doing a weekend getaway in Milwaukee.
