"Accor has categorized a handful of its properties around the world, including the Hotel de l’Opera in Hanoi, as members of its “MGallery” collection, the “m” standing for “memorable.” It’s one thing to say your hotel is memorable, but it’s another thing entirely to pull it off. This boutique-style hotel, however, really does demonstrate character, a singularly stylish vision that offers an extraordinary alternative to budget guesthouses or corporate monoliths." - Tablet Hotels
