Bilbao’s urban identity is defined by the contrast between its medieval heart and its grand 19th-century expansion across the Nervión estuary. When deciding where to stay in Bilbao, the choice almost always comes down to Casco Viejo (the Old Town, or Zazpikaleak) on the east bank, and Abando (the Ensanche) on the west bank.
The two districts are separated only by the Nervión river and connected by multiple pedestrian bridges, taking less than five minutes to walk between them over Puente del Arenal. However, their day-to-day lodging experience could not be more distinct. Casco Viejo is dense, pedestrianized, and atmospheric, centered on the neoclassical arcades of Plaza Nueva and the narrow flagstone corridors of the original Seven Streets. Abando, laid out in 1876 on an orderly grid, features wide tree-lined avenues, Bilbao’s primary financial and shopping axis (Gran Vía), and the city’s major rail and bus hubs.
Transit convenience also divides the two sides: while Casco Viejo has its own metro hub (Zazpikaleak/Casco Viejo) connecting to the Euskotren coastal lines, Abando hosts the primary arrival crossroads of the city. The Bizkaibus A3247 airport express terminates at Plaza Circular in Abando, making arrival with luggage significantly smoother on the west bank.
