Las Flores Hotel in downtown San Diego’s Gaslamp Quarter occupies an 1888 building at 725 Fourth Avenue designed by Irving Gill — the only solo architectural commission Gill completed in the district. The structure has served as furnished lodging without significant interruption since its construction, predating every other hotel on the Fourth Avenue hospitality strip that now includes Gaslamp Plaza Suites and a half-dozen other properties. The lot traces to an 1869 sale by city founder Alonzo Horton, passing through winemaker Theophile Verlaque and grocer Giovani Raffi before the current building rose as the Las Flores lodging house — later renamed the Hotel Cortland, the Altrude Hotel, and restored to its original name in 1979. Street-level commercial space currently houses a lounge operation, maintaining the Victorian-era pattern of ground-floor retail with upstairs guest rooms. That position between G and F streets at the Horton Plaza end of the quarter keeps the hotel within two blocks of the Gaslamp’s densest dining cluster, where Fifth Avenue anchors like Osteria Panevino draw the evening foot traffic that sustains the corridor’s lodging demand.
