This place was as described, and actually a little bigger than we expected. The location is perfect, as it is a short walk to attractions like Marathon Music Works, Nelson's Green Brier Distillery, and Antique Archaeology (from the show American Pickers). It's a short drive to a whole lot of restaurants and stores, too, as well as downtown Nashville.
The unit is very secure (in a gated complex) and clean. The shower is hot, and the bed is comfortable. The HVAC unit is a little louder than I had expected, but I think that's just because it's kind of an older building. It worked well, which is what is important. The kitchen is full of utensils, pots & pans, and dishes, so if you stop at the store, you can cook full meals here.
I'll look at this place again first the next time I book a trip back to Nashville!
