What a wonderful, dog-friendly home away from home that Sandy offers. While I only booked a single day, it was a nice place to chill out with my dogs, especially since the backyard is fenced in.
The bed I slept in was satisfactory, with the mattress being average in comfortability. There are train tracks close by and it is fairly active, but with that said, it's not obnoxiously loud inside and even a light sleeper like myself wasn't bothered by it.
There was an issue with cleanliness during my stay that I brought up with the host, but all in all, the place was mostly spotless.
If you're looking for a place to stay in Nashville, I would absolutely consider Sandy's place.
