We walked quite a distance in the rain to see the synagogue and museum, and we weren't disappointed. A guided tour is included in the price of admission, and our English-speaking guide was quite knowledgeable. The museum itself consisted of 7 rooms of artifacts on display, and the synagogue was both beautiful and of historic interest. Photography is not allowed, either inside the building or on the grounds - most likely for security reasons, but guidebooks, etc, are available in the gift shop. I doubt most people would make this their first point of interest to visit on a trip to Rome, but if time allows it's certainly worth checking it out.
