Catherine's apartment might not be right in the centre of Paris, but it is conveniently situated close to the metro, and directly across from a shopping centre.
The apartment itself is immaculately clean, and the bed was fresh and very comfortable.
Catherine was always available if I had any questions, and helped me navigate the city and book a shuttle back to the airport (all the stairs in the Paris metro were too much for me and my heavy bags).
I would definitely recommend Catherine's apartment to anyone who likes a clean and quiet space to retreat to after a long day exploring all the sights of Paris.
