Anya Firestone, Tour Guide and Star of ‘The Real Girlfriends of Paris,’ on ‘The Art of Drinking’

On a recent morning at the Louvre, Anya Firestone handed out bottles of Evian. “Because ‘the art of drinking’ begins with hydration,” she said.

Ms. Firestone, 34, a museum guide-conférencière (tour guide) and art integration strategist, wore rhinestone earrings in the shape of olive martinis, pink Manolo Blahniks, the Mini Bar clutch by Charlotte Olympia and a Marni dress printed with likenesses of Venus.

She escorted Matt Stanley, her client, and his Parisian date, Salomé Bes, 30, past the long lines at the museum’s entrance and toward the Code of Hammurabi.

Ms. Firestone was raised in the Hell’s Kitchen neighborhood Manhattan; her parents were actors. She first moved to Paris in 2010 after college at George Washington University, for an artist residency, during which she wrote poetry and sculpted oversize macarons. (People thought they were colorful hamburgers,” she said, explaining that the confection had not become popular yet.)

She worked briefly as an au pair, channeling Mary Poppins and Maria von Trapp, she said. But Ms. Firestone likened her current plot to the TV shows “Emily in Paris” — “Love her chutzpah, less her bucket hats,” she said of the protagonist —…
