The Keating Hotel by Pininfarina is most notable for its striking red and black interiors designed by the Italian car company behind Ferrari and Maserati. Just like the cars, this historic hotel's makeover is sleek and chic, with a sexy ambience. The industrial-style rooms have Italian luxuries such as Lavazza espresso machines and custom-designed glass rainfall showers. Not everyone will appreciate the lack of privacy some of the showers offer, though, and guests have to pay for upscale amenities (Wi-Fi, turndown service, the Lavazza espresso and tea, and a welcome amenity) by way of the nightly resort fee. The Gaslamp Quarter location is great for partying, but travelers who don't want to be in the same building as Coyote Ugly, which is bumping late into the night, should check out the nearby Andaz San Diego, or the eco-friendly Hotel Indigo.
