The central Eixample district is certainly crowded, but it's not hard to understand why. Color, energy and the visionary genius of Antoni Gaudí are present around every corner. From the magnificent Sagrada Familia to the wavy contours of the Casa Mila, Gaudí really went to town in the Eixample. However, to experience both Gaudí and the vibrant colors for which Barcelona is famous, stroll along the Passeig de Gracia and check out the Casa Batlló. Gaudi’s ‘House of Bones’ was not built from scratch, but rather an existing building remodeled and transformed by Gaudí. The result is spectacular. Restaurants, bars, and designer shops are always just a few steps away, while good public transit connections will have you exploring the rest of the city in no time at all.
