I will be in Rome in April with my husband and 10-year-old daughter. I see there is both a Da Vinci museum in Piazza del Popolo and a temporary Da Vinci exhibit in Palazzo della Cancelleria. I'm wondering which one is better. Also, I see mention of a Mona Lisa museum at Piazza Navona which also looks interesting, but I can't find any reviews of that. Any information would be greatly appreciated.
