Nathalie was an excellent host and very accommodating + responsive :) She messaged multiple times before our stay to check on bed arrangements etc., and personally gave us a tour of the beautiful apartment. The balconies open up to gorgeous views (including of the Eiffel, which I looked at on clear days)! She also gave recommendations on food and transport etc.
Absolutely enjoyed ourselves. It is an old building, but perfect for the true Parisian experience. There are small things that weren't within the host's control, like the unlit corridors outside the apartment and a slight sewage smell in the bathroom occasionally. But the place was clean, pleasant and cosy -- and conveniently located near Rue des Boulets station plus (a little further) Nation.
Fell in love with the apartment very quickly; looking forward to staying here again the next time we return to Paris. Highly recommend it!
