This is one of those overwhelming art galleries where there is too much too take in in one visit. We hired a private guide for the two of use and that really made the visit. We spent almost 4 hours with our guide, Gastone, and were never bored. We asked him to focus on the "best of Italy" and not only did he show us great art but he provided the historical and political context, which was invaluable to appreciating what was there. The Galleries have a roof top café (indoor & out) which is good place to take a break.
