What is the best time? For Lucio it is the one spent with his grandfather. They don't see each other often, so they take every opportunity to be together. Just like it happens on this day that grandfather Gabriele and his grandson Lucio spend in Venice delivering small objects to the restorer grandfather's clients. Readers, also helped by the beautiful illustrations, will find themselves walking with them through the streets of the city, discovering, in addition to the most famous areas of Venice, that it is really true that "time spent with family is the best time".
