The flat is in a wonderful quiet block with a sunny, south facing balcony which was great for having a delicious breakfast of fresh fruit (bought from a nearby market, 15 minutes walk away).
The flat is homely and clean, with all the amenities you could wish for. Audrey and Alexandre were very communicative and helpful and had put out welcoming sweets and apple juice, which was a lovely touch.
The immediate neighbourhood is quite quiet but very well connected on the Paris metro. However you are very close to the lively 11th arrondissement and the excellent Marais, which is a pleasant half hour walk back from after dinner.
We recommend the Blé Sucré boulangerie (15 minutes walk) which the internet said did the best croissants in Paris and which we can confirm after extensive taste testing.
