I had a great time at Carrie's place! The communication was super easy and quick and the place looks exactly like it does in the photos. The neighborhood is very conveniently located and the walk to downtown Nashville wasn't bad at all (~ 40 minutes and it's a straight shot).
You could hear some noise from the neighbors upstairs, but this was mentioned in other reviews, so I was prepared for it (and could have selected a different spot if I wasn't cool w/ it). If you're interested in hanging by the pool, make sure you check to see if it's open for the season. It wasn't when I stayed, but it made sense re: my timing (early spring).
I absolutely recommend this spot, and hope to come back again sometime!
