Sleek, masculine, and trendy with an L.A. sensibility, this hotel embodies San Francisco’s young professionals’ “work hard, play hard” motto by providing a proverbial adult playground for the tech crowd. For starters, it has an interactive lobby complete with a Plinko Game and a playroom, featuring a pool table, shuffleboard, and video games. Guest rooms start at a spacious 250 square feet and feature large butcher-block desks, pillow-top mattresses, smart TVs, and illy espresso machines; the large bathrooms feature mosaic-tiled walk-in showers. The sexy lobby bar and comfy-cool Cavalier restaurant also lure.
