Congreso
Leading from Plaza de Mayo is Avenida de Mayo a tree-lined boulevard packed with architectural gems that leads you to Argentina’s political heart,
Congreso. As you wander north, landmarks include the
Casa de la Cultura, which offers free tours, Café Tortoni (prepare to queue for coffee and
churros) as well as the Museo Mundial de Tango and the marvellous, eclectic, Palacio Barolo (book a private tour to see inside). The avenue ends at Plaza del Congreso, dominated by the Greco-Roman style Congreso Nacional (and possibly get caught up in a demonstration, a feature of life in BA).
For faded grandeur:Castelar
Spanish poet Federico García Lorca stayed at this pleasant, old-fashioned hotel located on a prime piece of Avenida de Mayo real estate. Rooms sport large and comfy beds, and there’s also a sauna and spa.
For budget stays: Bauen
This time-warp hotel was the bee’s knees in its heyday, until management closed it down in 2002. Employees, however, were having none of it and took it back over as a worker-led co-operative. Rooms are a misfitting array of styles, but the location and the price are top-notch.
