The apartment is absolutely perfect! situated in the best location in Paris, close to RER B (from CDG), Metro lines and buses! also walking distance from the Pantheon, Notre Dame, St. Chapple, Conciergerie, absolutely top location. It was super clean and very well equipped. Hervé was a wonderful host. he left very detailed instructions as for the check in, and made sure the apartment would be warm on my arrival. really wonderful. I really didn't mind the stairs, but it could be difficult for some people. I highly recommend this apartment :-)
