The Underground is clean, and it has some cool, fun decor. We aren't super familiar with Nashville and were only there a couple nights, but the location seemed good to us; near enough to drive downtown and visit the Ryman and the Johnny Cash Museum, but far enough out to be in a quiet neighborhood and get a good night's sleep. The bathroom and kitchenette were well supplied, and the beds were comfortable. Jessica is an excellent host and quick to respond to questions. Overall, a great experience!
