The One Barcelona, for proximity to modernist architecture in Eixample

Surrounded by the handsome modernist architecture of the diverse, upscale neighbourhood of Eixample, this five-star hotel is mere steps from the rippled-stone edifice of the Casa Milà and the pointy spires of the Casa de les Punxes, designed by Puig i Cadafalch. Marble-clad bathrooms with octagonal mirrors and a gold-and-neutral colour scheme define the rooms and suites; for views of the Sagrada Familia, nab the top-floor terrace suite, which comes with a jacuzzi on your private terrace, or reserve a table at the rooftop restaurant.
