Incredible experience. I chose to visit Galleria Borghese out of curiosity and oh boy how happy I am to have done it! The gallery is not big, but it is overwhelmingly gorgeous, the sculptures, the paintings, the walls, ceilings, the floor.... I found myself getting emotional from all this beauty! You are allowed to visit the gallery for two hours - please do not rush and use them to the max, it is really worth it. I think it is my favorite attraction in Rome.
