If you've ever fancied working from your very own palace, this is your chance. Originating from the 18th century, this majestic building once housed the country's aristocracy. Since its renovation in the 1990s, it's now an address for 21st century business. The traditional architecture has remained unchanged in order to keep its impressive character, however modern amenities and a striking glass roof now feature, flooding the central patio with natural light. Here, you can hold impromptu business meetings, or take things upstairs to your own office space and private meeting rooms. Securely leave your car in the underground parking, while you spend the evening exploring the surrounding old centre of Madrid. You've got Neptune Fountain to perch at and take some time out, or there's Cofidis Alczar Theater and Crculo de Bellas Artes Art Gallery if you want to get more stuck into local culture.
