We really liked Scarlett’s place. This is definitely the BEST location in 12 South. You're walkable to all the cutest coffee shops, stores & restaurants. Highly recommend it for this reason.
A couple of call-outs — the walls in this apartment are paper-thin, so you can hear everything above and below you. Below you is a cool restaurant called "bar taco" that plays music throughout the day, so it gives the apartment a bit of a vibe because you're always faintly able to hear what they're playing.
As far as the floor above... just hope you're on a similar schedule as the people upstairs! One morning the guests above us got up at 6am and as a result, so did we. It's a bit annoying but we got used to it.
