This place is awesome. It's walking distance going to Le Louvre, rue montorgueil , Notre Dame, Les Halles.
The place is really center of so many places in Paris. Plus, the metro is just 10 meters away. (Etienne Marcel station).
But, since it's an old apartment building, get ready to go up the stairs 6 floors. A real cardio workout specially if you have big luggages with you.
the hoise is well equiped. Good wifi too.
Maxime, though we didn't meet, was very accommodating.
I'd consider this place again when we go back.
