This place is a 15 minute walk to downtown, although in the summer heat it will nearly always be a 5-7 minute Lyft ride that cost $6-7. Be aware, the complex where it's located is very close to booking/release facility with barbed wire, but I'm general this area seems safe during the day.
Pros:
+Great amenities: hairdryer, straightener, shower and pool towels, kitchen/dinning equipments, scissors, bottle opening... you don't really need to bring much
+Quick and responsive communication: our group needed early check-in/drop off luggage early and shipping a package, Tyler (one of the managers) was very quick to respond to my messages and offered us a place to store our luggage (at a place less than 10 minute car ride away) before 11:30AM and a 11:30AM early check-in time.
+Specific instructions and early check-in: A few weeks prior to arrival , I received a detailed message regarding all the info I need to know about staying at this Airbnb. Everything is written clearly, wifi password is posted on the wall, it was super convenient.
+Fitness facility and pool: I did not get to use the gym. The decent-sizef pool (though it can get super crowded during the weekend) over-looking the river.
+Two super comfortable full-size (?) beds in the same room perfect for a group of 4 or less
Cons:
-The complex is near the train track and there are trains going by occasionally
-The bedroom is not completely enclosed and separated from the living room, so any sound from the living room can be heard clearly in the bedroom (not a bad thing, just be aware)
-Having to gather the trash and take off bedding prior to leaving is a hassle, especially when guests have super early flights as we did.
Overall, it was a great place and experience and I would highly recommend this place to people. Also, Nashville is such a fun place if you love to eat and enjoy live music.
