Metro
The metro station Pasteur (at the crossing of the line 12 and the line 6), 2 minutes on foot from the hotel Korner, will allow to access directly the Eiffel Tower, the Porte de Versailles and the Champs-Élysées. The Pasteur Institute and the Necker hospital are located in the surroundings as well. The Montparnasse station is a little further (7 minutes on foot) and is linked to many other lines (4,6,12,13)…
