Hovering on the invisible border between the Montparnasse and Saint-Germain neighborhoods, this adorable hotel is a quick walk to the Luxembourg Gardens and the delights of the Bon Marché department store. While maintaining the original detailing and mood of this 19th-century building, the period decor is spiced up with contemporary colors and textures, like a gold and purple version of traditional toile de jouy wallpaper, or old-fashioned stripes cheered up with lush velvet pillows and contemporary headboards. Off the lobby, a cozy reading room is available for quiet pursuits and discussion; nearby, the yoga room (equipped with mats, bricks and a big mirror) is open 24/7. Connecting rooms are available for families, as well as a furnished apartment for rent by the week or the month.
