This former auto garage in Nashville’s Gulch neighborhood was turned into a truly unique five-room boutique hotel in 2014, and it’s a real standout. No cold industrial vibes here: The high-ceilinged rooms—some have loft living spaces—are furnished with plush custom furniture and cozy rugs, and the spacious baths gleam with white subway tiles and vintage taps. There is no front desk, but guests receive a passcode for the entry keypad, and a concierge service is on call. A comfortable sitting area is furnished with a couch and board games, and a large sideboard is set with refreshments and coffee during the day, which makes the 404 the perfect spot for urban explorers. Guests can—and should—eat at the attached 404 Kitchen, housed in a shipping container and accessed through another keycode doorway. It’s one of the top eateries in the city.
