The book with maps of Paris was really useful. The bakers and supermarket were two minutes walk away. The best thing for us was the child's bedroom with all the toys, it made things so easy and our boy so happy.
Shower and bath kept everyone happy. Fish market at Rue Dejean was great. The flat was near metro, near shops. It was a great spot from which to do our sightseeing, but also chill out in the flat.
