We stayed in the flat for a week over new year as a couple, using the flat as a base to explore the city of Paris. For this the location is superb. It is right down the street from a metro station, and close to the beautiful Pere Lachaise Cemetary. The street itself is full of local shops (Bakers, cheese makers, Patisseries). There are lots of local bars and Bistros which, being outside of the tourist hot spots, are not as expensive as other parts of Central Paris. E.g. La Nouvelle Etoile for delicious Onion Soup.
The flat itself is decently sized. The kitchen is rather small, however it has a gas hob and oven and sufficient utensils to allow home cooking, which is great if you want to save money on dinners, or to prepare a packed lunch. The bedroom, and living spaces were very comfortable and stylishly decorated throughout. The whole space was very clean and warm despite the cold weather outside.
Jessica was very quick to respond to questions via the air bnb site, and had laid out towels and bedding for us on arrival.
Overall, we'd absolutely recommend the flat for a stay in short to medium stay in Paris.
