Open since the 1960s, the Arion Resort & Spa is named after the legendary poet. Its infrastructures were updated by architect Manolis Vourekas five years after its opening. At the time, it welcomed many famous guests, such as Nelson Mandela, Frank Sinatra, Jane Fonda, Jackie Onassis and Tony Blair. In 2004, the P. Masourides Company architecture firm and the Hirsch Bedner Associates interior design company carried out some major renovations. Their goal was to retain the establishment's classic style all while adding a touch of modernity. After it was re-opened in 2006, the Arion was welcomed into the Starwood Luxury Collection family. Today it belongs to the huge Astir Palace complex, like the Westin Athens and, in 2016, the W. The grounds extend over 74 acres on a private peninsula.
