Louis president Debi Greenberg quickly makes it clear that the decision to open a 200-square-foot boutique inside the Mandarin Oriental Boston on Boylston Street is not because she’s missing the Back Bay. (You’ll recall that her flagship store moved to Fan Pier in 2010.) She simply got an offer that was too good to refuse.

“The Mandarin called us up and asked us if we’d like to have a boutique,” Greenberg says. “We thought it would be a perfect advertisement of who we are, what we do, and direct guests to the store if they need something more.”

The satellite Louis, located in a former magazine shop in the hotel, sells luxury items that travelers may find they left home without, such as pajamas, toothpaste, basic white shirts, ties, sweaters, and shoes that are appropriately comfortable for strolling the city.

“It’s all the things that we have that bring their lifestyle to them when they’re traveling,” Greenberg says. “Apothecaries, perfumes, creams, candles, books, CDs. We’re still trying to figure out how it will all work in the space.”

And then there are the things that are not necessarily essential, such as perfume and jewelry, but are still nice to have around.

“I always love walking around these small boutiques in luxury hotels,” says Greenberg. “It’s an indulgent diversion.”
