We had a wonderful stay at Frédéric's absolutely lovely apartment! The location was great (an easy walk from Gare du Nord), and although we were only there for one night, Frédéric was very welcoming when we arrived and made the whole check in/check out process very smooth and straightforward, even though he himself was out when we left. His bathroom is AMAZING, and the bed was very comfortable! We only met his sweet kitty in passing, alas, but all the more reason to come back at some point. :) Merci beaucoup, Frédéric!!
