"21C is perfectly located in downtown Cincinnati right across from the Arnoff center, and a convenient walk to great American ballpark. There are so many restaurants close by and a really good Irish pub right next-door. Highly recommend it for your next day and the workout gym was pretty well equipped for a short weekend stay.
The valet parking was a little bit expensive, but overall the hotel is definitely worth it.
If you can Uber from the airport to 21C that would be my recommendation because everything else is conveniently located."
