One of the most recent additions to Marriott's Autograph Collection, Hotel Cotton House Barcelona is housed in an iconic 19th century building that was formerly the headquarters of the Association of Cotton Manufacturers. Staying true to the hotel's origins, designer Lázaro Rosa-Violán was commissioned to design the hotel in a contemporary, sophisticated style. With 83 luxurious bedrooms including seven suites, guests make their entrance through a stunning hall of mirrors that leads to an octagonal hall with two sweeping staircases. The hotel also houses an elegant library, a restaurant and cocktail bar, a conservatory, a terrace with lush vegetation, as well as a rooftop pool.
