Excellent location. Walking distance from Seine, Louvre, Musee D'Orsay, Pantheon, Notre Dame. And the street itself is a site.
While the rooms with a view to the street may be noisy, the rooms facing the inside do not have any kind of view (ugly courtyard) - but are very silent at night.
The shower flooded the whole bathroom, but this was quite insignificant for the whole.
We had a wonderful time !
