The Radisson Madison is bang-for-buck the best hotel out there and my personal favorite to stay at. All of the staff rock and the hotel does all of the little details better than most. Ie we got a room package that included "chocolates" and ended up getting a beautifully decorated platter of chocolate-covered strawberries. The Radisson Madison KILLS it. 10/10 would recommend.
One aside if any Radisson managers happen to be reading this, we got room service for breakfast and a 20% gratuity as well as a room service/delivery charge was included. This seemed a bit odd because I still wanted to personally tip the person who brought the food to us (it's never clear if they actually see those "included tips") so id recommend not automatically including gratuity in a room service bill.
To everyone else, I reiterate, go to the Radisson Madison, it's the best.
