I thoroughly recommend Sabine’s apartment as an option for your stay in Paris. Bastille is the perfect base - within touching distance of Aligre market, close to the river and in sight of Paris’ big monuments. The restaurants nearby - Septime, Clamato, East Mamma - are all delicious too.
The apartment itself would be excellent for longer stays as the kitchen facilities are top spec, so you can buy ingredients from the market to prepare.
When I next come back to Paris, I’ll immediately try and book here again
