My wife and I flew to Nashville for a friend's destination wedding. Pine St is a great location!
There are plenty of great restaurants within walking distance. I highly recommend Biscuit Love. It's delicious and it's only a two minute walk from the building. The line gets can get long fast, so plan around that.
The apartment we stayed in was cozy and clean. It's a small studio, but feels spacious. The bed was really comfy. AC was great during the hot days in between our events.
We would stay here again if we had an event in Nashville.
