[Spambayes] OT: hotels near subway in Boston?

So I'm booking travel for this spam conference next month, and I'm learning that I probably don't want to rent a car in Boston. The country being very automobile-happy, though, I can't find any hotels that advertise proximity to the subway. Are there any Boston-area residents on the list who can recommend a place to stay that's near the subway? I'm a tourist so I can't handle a lot of bus transfers. Thanks Neale
