Travel in Nashville is generally easy to navigate. The airport (BNA) is located on the East side of town and is within 20 minutes end-to-end of the city. Public transportation is very minimal, but Ubers and Lyfts are always available! You are more than welcome to stay in whatever part of town you like! Here are some hotels near downtown that have great reviews! For less expensive options, going further from downtown is helpful!
