I would give the collection itself 5 stars, but the museum itself, the building and arrangement 3 stars.
The collection is huge, consisting of both paintings and three-dimensional art ranging from the Neapolitan Times until today. Several floors and rooms present the large variety of art the Musuem of Fine Arts offers.
The building itself though I find weirdly arranged and though I loved the art I didn't feel too comfortable walking around. The floors are fairly confusing and the "modern mix" I found very much "trying too hard".
I wish I could see the collection in another building and arrangement, then it would be a clear 5/5 stars.
