Mathieu deserves his five star rating. Extremely responsive. Totally available for any issues. Location is terrific if you want to experience how Parisians live. Multiple areas to enjoy food and wine. Easily accessible to anywhere if you enjoy walking. I did not use the train system during my stay but I quite enjoy walking and the great charm of Paris is the streets and the wide Boulevards.
I have had tremendous success throughout France with Airbnb and this is no exception. Just remember this is someone’s home/apartment.
