This finely detailed Italianate was the setting for many lavish parties when it was owned by Frederico Barreda, Minister Plenipotentiary from Spain and Peru to the Court of Saint James and the United States.

The upper flat was used by Madame Barreda and her daughter, while the Polks lived in the lower.
