Discerning travellers with an inclination for slick design, fine food and decadent experiences need look no further than Altis Belém Hotel and Spa. Here, architects have fashioned attractive cube-like structures with clever features like the ‘waves of lace’ shutters, going hand-in-hand with huge walls of glass that frame the Tagus River outside. Black and white dominate, but the monochrome palette is interspersed with arty, colourful walls that are meant to represent Portugal’s old-world colonies; across South America to Arabia, Africa to Asia. Bold furnishings are met with luxurious amenities, like huge deep-soak tubs in the glass-panelled en suites or even sleek hot tubs on private balconies.
