My son (age 9) is keen to visit the Leonardo Da Vinci museum in Florence, however I've just realised that there are 2 in Florence. Is the museum on Via dei Servi new??, it doesn't have many reviews compared to the one on Via Cavour. They both seem to be suited to children. My daughter ( age 16) likes the sound of the gift shop at the one on Via Cavour. However another reviewer thinks the Via dei Servi one is best for children. Has anyone been to both? Any recomendations?
