We really enjoyed our stay in this little cottage, which was perfect for our needs. For a location so close to downtown, the price can't be beat.
Regarding the neighborhood -- we didn't feel unsafe, but the area is kind of isolated and bordering on industrial, and we probably wouldn't walk around the neighborhood at night. But like other reviewers have said, just exercise the usual awareness that you would in any other big city. The house was very convenient for getting to all of the central Nashville locations by car.
There are train tracks a couple hundred feet behind the house, with a lot of train traffic all day and night, and you will hear many trains tooting their horns and sometimes just sitting there rumbling. I like that, but others might not.
The place itself was nicely furnished and had everything we needed. Tall people might have issues with the shower.
Overall, Debbie's place was a great value and a fine place to call home for a few days.
