Clemence's apartment was exactly as pictured and described. It IS cosy, yet not at all cramped, with a rather large kitchen for a Parisian flat. Because the terrace overlooks a beautiful green courtyard, the place is light and airy and you get a nice breeze if you open the terrace doors. The apartment was clean, the bed was very comfortable, and there is even a bidet in the bathroom! On a quiet street in a very busy part of town, I felt at ease coming and going, even late at night, which was important to me as a woman staying alone.
As for Clemence, she was there precisely when she said she would be for my check-in and check-out, and even helped me take my luggage 2 blocks away to the taxi stand when I left.
I whole heartedly recommend Clemence's apartment.
