By "Boston" do you mean in the city proper and/or very convenient to downtown? Then Calumet in Cambridge is it, probably. They have one small case of film now and a smattering of used equipment. The Hunt branch in Harvard Sq has very little film left; I haven't been by the branch in Kenmore Sq in a while. The mother ship in Melrose is a long subway ride + walk away. EP Levine has some film and generally a large amount of used equipment but is a long way from downtown and very inconvenient to get to if you don't have a car. The pricing on their used gear is wildly uneven, and they'll sometimes let things sit for a very long time without adjusting to market. Some of it is on consignment. Newtonville Camera still has film and also some used equipment, which is overwhelmingly 35mm; they're also far from downtown and inconvenient to get to via public transport.
Likely not relevant to someone visiting from Italy, but with the possible exception of Hunt in Melrose, where I haven't been for a while, all of these are down to a pathetically small selection of darkroom consumables. Newtonville was the least bad last time I looked, but they were shrinking fast, so I wouldn't hazard a guess as to what you'd find there today.
