i recommend the doria pamphylli (sp) art gallery on the corso in rome..get the earphones and hear interesting history of the artworks and the building...since i love caravaggio, i love the french church near the piazza navona (i believe it is St Louis de France) which has three gorgeous paintings in the rear chapel, and the church which stands alone at the piazza del popolo which has two, one of st paul being blinded by the light...very moving. and the church of st paul outside the walls is a holy place! also the little museum to the right of the spanish steps where i believe keats died (could have been shelley
) if you like goethe, he also lived further down the street toward piazza del popolo on the right and you can see his apt and some interesting drawings by his roommates....there is a treasure around every corner...give yourselves time to enjoy!
