Leave it to the Four Seasons to take four historic buildings and transform them into one sensational showpiece. This brand is synonymous with service and style, and the Madrid property is no exception. Here, landmark architecture and historical details seamlessly blend with contemporary panache, especially in the supremely elegant guestrooms and suites. Its city center location is a boon for those exploring Madrid by foot, while the spa and pool await for some downtime. The hotel’s extensive art collection features a number of rising Spanish artists; equally eye-catching is the view from the buzzing rooftop restaurant.
