It's a very clean and very comfortable small hotel room in a very convenient location. There is a metro stop less than a block away and a ton of restaurants nearby and all the way down Rue du Faubourg Montmartre. It's also about a half hour walk to the Louvre and Musée de l'Orangerie so it's easy to get to the sights.
The bed is comfy but it is a narrow twin bed that can only hold one person. Don't try to cram two people into this single room.
