The flat is great for a weekend in Paris or a longer stay. Very well decorated and furbished, it’s super clean and big enough for a couple. The location is very convenient since it’s close to the subway station Denfert-Rochereau accessible from the 2 airports (RER B) and it’s in one of the nicest street in the Rive Gauche full of restaurants and small food shops.
I would definitely go back to Antoine’s for another stay in Paris.
