I was there for one night and checked in late so I really didn't have a lot of time there. It was a great location, though! I had a rental car and got a parking spot right out front of the apartment block and there were extra spots along there to park. I felt fine about leaving the car out there and didn't have any issues.
I don't know if I would have walked around that exact area a whole lot as a solo female but it is only a few blocks from areas that I would feel a lot safer to walk around and it's a very convenient location in the city. A short Uber ride will get you to a ton of the must-see Nashville spots and downtown area.
The apartment was spacious and clean and the bar cart is a thoughtful touch! Wish I could have spent more time here. Kaleb has great communication :) Can't wait to get back to Nashville!
