The apartment was exactly the same as mentioned in the post.
The Host Mrs.Jacqueline Poncet was extremely kind and explained all the details with a great deal of patience. Due to Air France airline strike our flight was delayed by a couple of hours but she was still available in the apartment to receive us warmly and hand over the keys. Mrs. Jacqueline also helped us with maps of Paris. I'm eagerly looking forward to my next visit to Mrs. Jacqueline's apartment for all my future trips.
