Modern design and furnishings mesh perfectly with historic surroundings at The Keating. Housed in a building that dates to 1890, this upscale hotel was crafted out of its historic bones by the design team of Pininfarina, perhaps best known for its work with Ferrari and Maserati. Resin-sealed cement floors, black-out shades, stainless steel custom furniture, Bang & Olufsen sound systems, and ridiculously beautiful bathing areas dominate the various rooms — referred to here as Stanzas — and suites. While it does offer several dining and drinking establishments of its own, its location in the heart of the Gaslamp Quarter puts it within walking distance of hundreds of bars and restaurants, so you don't have to worry if the in-house options don't work for you.
