In Nashville for conference two weeks ago. While I didn't stay here, I popped my head into the lobby while exploring the Gulch area post-Sunday brunch to say that I've "seen" a Caption. Agree with
snare5117 that location is great: close enough to the hot spots along Broadway (and for that matter the Insta-snapping crowd in the Gulch itself) to be very walkable but removed from the immediacy of it all. Snapped photo from "library" corner, with ample comfy chairs and books and games at hand.
