From the rooftop, spectacular views of Notre Dame, especially lit up at night. Modern design and technology made the space accessible, comfortable and quiet, even in the midst of the jubilant Quartier Latin. Great running nearby along the Seine with Paris Plages in session, topped off of course with 76 stairs up to the Triplex. First-rate dining at Le Récamier and Atelier Maître Albert; and can’t beat the croissants at Bertrand’s. A cool way to do the heart of Paris for a change.
