Katy's apartment in East Nashville may be the nicest Airbnb I've stayed at in the United States. The place was comfortable, quiet, and amazingly well-decorated - funky, fun, and festive. The beds were great, and there were air purifiers in both bedrooms.
While I never met Katy, she quickly answered any questions I had and made great suggestions for places to go. She even left breakfast items and toiletries.
I'd stay here again in a heartbeat when I'm in Nashville.
