It was Vera Iachia, the decorator behind all the beautiful houses in seaside Comporta (as well as the resort town’s best shop, Space & Art), who recommended Embaixada (Praça do Príncipe Real 26; 351-9/6530-9154). The concept store occupies a newly converted 19th-century palace, with two floors of rooms given over to different (and largely inexpensive) shops for clothing, accessories and homewares, as well as a lovely one-room organic spa, Organii Lounge (1351-9/1293-2221). A Vida Portuguesa (Largo do Intendente Pina Manique 23; 351-21/ 197-4512) is Iachia’s other favorite. The latest outpost of this brilliant multibrand boutique, in a former tile factory in the Mouraria neighborhood, delivers an Iberian version of Colette meets Dean & DeLuca, curated by Catarina Portas, who is among Lisbon’s great tastemakers. Its wares—“genuine and touching products of original Portuguese creation” reads the manifesto—range from Claus Porto soaps and canned bacalhau (salted cod) in vintage Tricana packaging to Coelima bed linen and exquisite sky-blue and sea-green chiseled wineglasses. For antiques, Solar (Rua Dom Pedro V 70; 351-21/346-5552) specializes in Portuguese porcelain tiles from the 15th to 19th centuries. The almost 200-year-old fine-porcelain producer Vista Alegre (Largo do Chiado 20-23; 351-21/346-1401) collaborates with contemporary artists, like Joana Vasconcelos, to create elegantly patterned table- and glassware. Sharp-eyed foraging usually uncovers something compelling in the bric-a-brac at the Feira da Ladra flea market (near the church of São Vicente de Fora) on Tuesdays and Saturdays from 6 a.m. to 5 p.m. There is a vintage-poster and books seller, Eduardo Martinho Alfarrabista (Campo de Santa Clara, Store 3; 351-21/419-1873), who has lithographs packed with 1950s color. The other standout boutique is Leitão & Irmão (Largo do Chiado 16-17; 351-21/325-7870), with its pretty heart-shaped silver filigree earrings—the city’s equivalent of the Tiffany teardrop.
