Santas Negras is a homeware and fashion shop in La Juanita, the stretch of houses and businesses on Ruta 10 just before the village of José Ignacio. It sits on Camino Saiz Martínez at the corner of Los Lobos, on the same grounds as the restaurant Tres. According to the shop itself, it is run by Patricia Torres, a Uruguayan interior designer, and Paula Martini, an Argentine textile designer, as a kind of design flea market: decorative objects, textiles by weavers from rural Uruguay, pieces restored together with local artisans, Martini's clothing line made in the area and finds brought from Scotland, Mexico or Vietnam.

According to the listing, the shop opens all year, every day from 11 am to 8 pm, while the restaurant on the same grounds is seasonal; the seasons here are the reverse of Europe's, so the quiet months are the southern winter, June to August. Stock and prices are checked through the contact on this listing; the portal does not publish them. Other shops in the area are in the homeware and design selection.
