A lovely, calm space (especially in the winter) I loved taking a long bath and rolling into bed each night. The bed is super comfortable although the Wi-Fi in the bedroom is a little inconsistent.
Love the Aesop products!
Keep in mind, the bedroom has no window so if you need fresh air and natural light, you can sleep on the pullout sofa in the upstairs lounge.
The neighborhood is wonderful with many good restaurants and boutiques.
I would absolutely return to Louis' flat on my next stay in Paris.
