This place worked very well for our group of 12 travelers (a Scout group of 5 adults and 6 teenage youth). We used the 4 bedrooms, 2 pullout couches, and two rollaway beds/cots to the fullest. The beds were comfortable - didn't hear any complaints from the group.
A good-sized grocery store (Kroger's) is only 8 minutes away by car, so that worked well for getting breakfast + snacks for our group. Downtown Nashville was only about that same distance the other direction, and we had fun touring there. All-in-all it worked great.
There was some wear-and-tear from previous renters in a few places, but it didn't really get in our way of enjoying our stay.
