We had a great stay in Nashville. The three of us had plenty of room to stretch out each day after exploring the city. Off street parking was provided for our rental car. Using Lyft was also very convenient to get downtown if needing to avoid parking hassles.
The Music Row neighborhood is quite nice. Plenty of dining options nearby. It provides the perfect complement to the hustle and bustle of downtown.
I'd highly recommend asking the hosts where they might be performing while you're in Nashville. We did and it was a highlight for us.
