Google has always given bad directions around Boston. It's been getting a lot better. Up until a couple of years ago I found it to be pretty much worthless in the Boston area, even when it did happen to get the right address (which, in the city of Boston itself, was a crapshoot). These days, it's right more often than not. But I still would never trust it without a lot of double-checking, and comparing against directions a human has written or told me.
