My husband and I had a lovely kids-free weekend at Bree's AirBnB. The place was clean, modern and comfortable. It had all the amenities you could want - including items to cook which we did not use :) Bree accommodated an earlier than check-in bag drop which was very much appreciated. She had some nice suggestions for things to do posted on a chalk board on the wall.
The location was central to most areas of Nashville, if you had a car. We did not and found the area to not be exactly walkable; we walked quite a bit anyway though as the weather was so nice. The nearest point of interest - The Gulch or Broadway for example - was about a mile away. Ridesharing was very easy in Nashville and by car everywhere we wanted to go was about a 10 minute ride.
Aside from that small point, which could mostly be attributed to our not knowing Nashville, we had a wonderful time and it was a great base for exploring Music City!
