Italian architect Nicola Bigaglia's 1904 Valle Flor Palace – now a National Monument – is easily Lisbon's most historically stunning luxury property. Staying here is like sleeping in a painting. From the Parisian-evoking saloon with red velvet inlaid chairs to the stunning pool (a former aristocratic lake) to the original frescoes, antique paintings, stained glass and rare exotic woods, momentous detail and lavish excess rule.
The Versailles-like gardens hosts picnic-style summer brunches and BBQs – open to the public – so if you can't splash out for a room, treat yourself to a day of regal eats instead.
