"High above the city, Palacio Belmonte was built for the aristocratic Cabral family in 1449, and has been enlarged and refined over the centuries. There are myriad terraces and azulejo-tiled staterooms, along with a pool shaded by the orange trees, an immense library and 10 characterful bedrooms, including one with 360-degree views over the Alfama neighbourhood and the River Tagus. The most fantastical suite, Ricardo Reis, has centuries-old frescoes, discovered beneath layers of flaking paint during a renovation. It's little wonder guests want to live here forever."
