A metaphor to start: when I first entered the apartment, I spotted a big basket of granny smith apples on a table across the room. When I neared the basket, the apples turned out to be plastic.
The apartment is clean and modern. it's situated in a modern but charmless apartment building of--I think--200 units (a few units set aside for short-term rentals).
The location is great, easy walking distance to downtown Nashville and its attractions, and plenty of restaurants nearby.
The hosts were responsive communicators, and even emailed daily to see how things were going, but quite a bit of the messaging seemed to be lists of rules with penalties for not following them.
Getting into the place the first time seemed to require solving a series of puzzles--this was frustrating for a weary traveler,
Overall I would recommend the place for its location and for a clean and modern place to stay. However, I would look elsewhere if you want something more personal.
