My second stay chez Catherine, close to the place de la Nation. The neighborhood is great, with local street markets, many good shops, and decent restaurants. You stay in a Parisian neighborhood, not a tourist area, yet Nation is only a 30-minute walk to central places like the Marais. In terms of the Metro, Nation provides amazing convenience: the RER A line gets you to Chatelet in two stops, and coming from the airport, you just cross the platform at Chatelet (from the RER C) and take the A train [sorry, couldn't resist] to Nation. Not far away, you have Gare de Lyon, which also has line 14, another quick way to central Paris. The elevated green walkway is only about 5 minutes away - simply lovely on a sunny day [note: it is closed during high winds]. The apartment is more like a maisonette, with a large, light-filled main floor and a bedroom suite downstairs [hint: if one of you is upstairs and the other sleeping, cover the two skylights with a blanket]. In two visits, each of about 10 days, everything has worked perfectly: capacious fridge, convection stove, toaster, tv. [We did not use the washing machine, but I did so the last time.] The weather was not such that we were outside in the small (and lovely) garden, but in warmer months you'd have even more usable space. Catherine's place is Airbnb at its best: someone's actual home, rented for short spells at given moments in the year. The couple could not be more gracious or accommodating hosts.
