Gaslamp Plaza Suites in downtown San Diego's Gaslamp Quarter occupies an 11-story landmark erected in 1913 as the city's first skyscraper and listed on the National Register of Historic Places. Original marble walls, brass elevator doors, Australian gumwood millwork, and coffered ceilings survive from the building's years as San Diego Trust & Savings Bank and later the Jewelers' Exchange — a preservation standard shared by only a handful of downtown properties, including the 1910 Horton Grand Hotel. The 1988 conversion carved 64 suites from the former office floors, each equipped with a microwave, mini-refrigerator, and separate seating area, with upper-floor units offering downtown and harbor views through the original window casements. Ground-floor tenants include The Melting Pot fondue restaurant and the Syrah Wine Parlor, giving the building an integrated dining-and-lodging identity that echoes the grand-hotel tradition at nearby The US Grant. A rooftop terrace with panoramic views of the Gaslamp Quarter and San Diego Bay doubles as a continental-breakfast venue, and a 15-person executive boardroom anchors the mezzanine level for small corporate retreats.
