21c is a marriage of art gallery and luxury hotel, with the installations and art scattered around the hotel including some really fabulous pieces. The room rate is not really inexpensive, but frankly the room rates in Louisville are a little inflated and are all in the same price range of 21c. The rooms are exceptionally well appointed with good eye to detail (e.g., the toiletries are really quite good). While these are in many ways bourgeois adult digs, plenty of kids would be fascinated by the space and many of the works (and I suspect some might not be to the taste of ever reflective pre-teen). The self-parking was only $5 a night (as opposed to $25 for the valet); room service breakfast we had was frankly underwhelming and pricy.
