In the sitting room, a steel-and-ostrich-egg mirror hangs above a sofa upholstered in a 1960s David Hicks fabric; the Jacob Frères armchair is covered in a Rubelli velvet, and the cocktail table is from the ’70s. The artworks include paintings by Xavier Vilató, bottom left, and José María Yturralde, center, and a Josep Maria Subirachs engraving and Miguel Macaya painting, right.
