Nashville has a wonderful mix of charm and energy.
I moved to Nashville ten years ago. I joke that I want to make a bumper stick which reads, "Not from Nashville, but I got here as quick as I could" :) I have lived in three different neighborhoods in the greater downtown area: The Gulch, SoBro (highish a block off Broadway), and currently SoBro (Rutledge Hill). I have probably been down every street and back road at least once - each area of the city has it's different amenities and appeal. I like townhouse living as opposed to high-rise, and like the quite feel of a residential community but still close the all fun of downtown.
Theres's a of fun things to do here, and I haven't done and seen them all ...yet! I hope my local hints and insights help you have a great experience of Nashville. And I hope that you discovery something new, some new restaurant or bar that I have yet to visit, and I hope you let me in on the secret! :)
