I'll review the listing and the experience separately because they would get two different ratings. Short version: the listing serves its purpose as a place to stay while exploring Nashville but I wouldn't stay one of these hosts' listings again.
Listing:
The location was really convenient for everything we wanted to do in Nashville since we had a car. If you're just walking, expect to use a ride service. Pay attention to the details in the listing. The driveway is very steep and sand and dirt will trek into the house since the area immediately outside of it is dusty. Wildlife friends will definitely stop by. The internet dropped for a few hours which was inconvenient since I was working during my stay and the smoke detector started beeping due to a low battery and was then just removed, not replaced. There weren't sheets for the futon bed or the additional pillows but otherwise the amenities were all there. Also a heads up that the floor slants so if you are sharing the bed you'll be rolling onto one person. The space is pretty small and dark but serves for somewhere to stay while you're out and about visiting.
Experience:
The experience with the hosts was not positive. Though they'll probably refute this, I found the hosts communication to be lacking. We had to change our reservation dates and they told us that we were going to have to pay more per night than our original reservation, though when I put in the change request I could see those dates had a lower rate. I was fine with keeping the original reservations cost but it was disingenuous and untruthful to say that the new days were actually more expensive. For the internet issue, the hosts handled that I think as quickly as they could. When we had the issue with the smoke detector, they said they would stop by to fix it but just removed it without saying that was the resolution. Apparently there are other detectors in other parts of the house but to me that is still a safety hazard. Finally, the end of the trip was really sour because the hosts tried to charge us a fee for leaving late though we vacated prior to the required time because we had a flight that boarded at checkout time. I got off of my flight to a patronizing voicemail saying that I would be charged and "would've been even if I had requested late check out ahead of time". Again, we had already vacated so I don't know what incorrect information the hosts got or why they would approach a visitor that way. It left a really sour taste in my mouth and I would not stay at one of their listings again.
