About the property

What makes Marriott Buenos Aires Downtown worth the points.

The hotel sits in the heart of Buenos Aires' business and commercial district on Avenida 9 de Julio, placing guests within easy walking distance of the Obelisco, Teatro Colón, Palacio de Justicia, and connections to Casa Rosada and Plaza de Mayo along Avenida de Mayo. Nearby pedestrian areas include Florida Street and Galerías Pacífico, with metro lines and rail stations such as Retiro and Constitución offering further access. The neighborhood is noted as highly central for sightseeing yet hectic and loud due to its role as a busy business hub. Rooms feature modern decor suited to business and leisure travelers, with smoke-free policies, complimentary in-room Wi-Fi, and select units offering views toward the Obelisco and Teatro Colón. Signature amenities center on the Nivel 23 indoor rooftop pool, which is heated and includes lifeguard service and towels, alongside the Nivel 23 Club & Spa offering massages, facials, body treatments, and a 24-hour fitness center equipped with cardio and strength machines plus sauna facilities. On-site dining includes La Luciernaga and TOMO 1 serving breakfast through dinner with local Argentine and international options, plus the Celtic Bar and a poolside bar and terrace for drinks with city views. The property is positioned as the primary Marriott option for guests seeking an upscale stay directly by the Obelisk with standard elite recognition for Bonvoy members.
