Once known as a haunt for the country's greatest matadors, this hotel is a tribute to the grand architecture of the early twentieth century. But that doesn't mean it's stuck in time. In the hands of the Meliá Hotels group, this landmark offers many a design surprise, from the mounted bull heads in the ME Lounge to the simple elegance of the guest room décor. We also like the contemporary bordello-esque atmosphere and lighting at ME Restaurant & Lounge — a favorite with visiting celebs. For more casual fare, head to The Roof (by way of private elevator) for cocktails under the stars.
