We are a family of six and we found the apartment very good for our purposes. It would be best for four people. The kitchen is small but functional and there's a good supply of pots, pans and crockery. The other rooms are fairly spacious, partly because of the rather open nature of the apartment.
The location is really good. We weren't looking to dine out, rather we shopped a lot at the nearby LIDL and local bakers. It's in a special and beautiful part of Paris within an easy walk of some great parks - Buttes Chaumont, Belleville and Villette.
We found Virginie to be a wonderful host, kind, charming and helpful.
The wifi internet connection in the apartment worked quite well for us, with only the odd hiccup.
We weren't overly disturbed by noise from outside. It might be more of an issue in Summer. The street, rue de Mouzaia, becomes surprisingly busy about 7.30am.
We ran out of hot water a few times and the keys took a bit of getting used to . On the whole we had a great stay in Paris helped by this lovely apartment.
