Great location! 2 blocks from Broadway, incredibly close to the Country Music Hall of Fame, Bridgestone Arena and Nissan Stadium and across from a reasonably priced parking garage ($16 for 24 hours). MAKE SURE YOU FIND PARKING BEFORE CHECKING IN. I got a $60 ticket and was only parked illegally for 5 mins (apparently this short time frame is typical for the area).
The apartment itself is in great condition and in a nice building. Check-in was easy if you carefully follow the instructions. Be prepared for spotty WiFi, so don't plan on connecting too many devices. Additionally, the pullout couch isn't really big enough to fit two full grown people. My friend and I had to share, and we're both over 6 feet tall, and it was not comfortable. I'd recommend this apartment to a group of 3, but a group of 4 might have a tougher time.
Besides that, I would recommend booking this apartment. The location was great for checking out Downtown Nashville and within very reasonable walking distance from Broadway (no worrying about late night Uber/Lyft).
Additionally, Amanda is a great host! She responded very promptly to inquiries and was incredibly cheerful.
