I stayed at Sara's place for over a week during AmericanaFest and it made a perfect home base. The East Nashville neighbourhood is very walkable - lots of restaurants, music venues and independent shops - and it was easy to use Uber to go into downtown (10 mins/$10ish).
The apartment is a lovely space. Nice bathroom with strong shower. A good kitchen. Comfy bed. Lots of light.
I would definitely stay here again.
