USA Hostels San Diego in downtown San Diego's Gaslamp Quarter occupies the 1887 Llewelyn Building at 726 Fifth Avenue, a Victorian-era structure with a double staircase, skylit atrium, and a documented history as a former Stingaree-district brothel. The property — founded in 1994 as Grand Pacific Hostel and later renamed USA Hostels before its current Gaslamp Hostel rebrand — houses 23 rooms across dormitory and private configurations, with each bunk built as a privacy pod equipped with individual lighting, a shelf, an electrical outlet, and a curtain, running a budget-travel format on the same Fifth Avenue strip where Gaslamp Burger serves its late-night griddle menu. A fully stocked shared kitchen with stovetop, microwave, toaster, and guest refrigerator supplements the complimentary continental breakfast program. Themed dormitories reference San Diego culture — Comic-Con, Taco Tuesday, Día de los Muertos, and the Kumeyaay indigenous heritage — and the property is one of the few Gaslamp Quarter hostels with central air conditioning throughout. The hostel's Fifth Avenue address puts Petco Park within a five-minute walk and the convention-week nightlife circuit — including the live-music and event programming at House of Blues San Diego — within the surrounding Gaslamp Quarter blocks. Full-building group bookings convert all 23 rooms for backpacker crews and student travel parties staging multi-day itineraries through downtown San Diego's waterfront attractions.
