Kat'e apartment is just as depicted. It is a comfortable stay for two, with basic amenities and comfortable furniture. My mom and I stayed for two nights in February and saw much of the city on foot from Kate's apartment.
The location was ultimately not idea for us, perhaps in part because it was frigidly cold in Nashville the weekend that we stayed. It made the 1.5 mile walk into town more difficult. While Kate's apartment is adorable, the section of Nashville doesn't feel very neighborhoody and I ultimately felt there wasn't anything I was interested in seeing/experiencing nearby, so all our jaunts were to other parts of the city.
Lastly, the apartment is unheated (except for a very noisy fan in the bathroom), which I assume is not an issue for 95% of the year. On the first day of our trip, the high was 30 degrees and so the spaceheater could not adequately heat the apartment.
