From the thread title I thought this was about the airport. We have no city named BOS in New England, and AFAIK in the U.S. We have a city named Boston, though. Oh, that's where you're really going!
Nobody, but nobody, around here refers to Boston by its airport code.

Woburn is way out of Boston and no place to stay unless you have a specific reason to be there. (I know some hotels call themselves "Woburn/Boston." That's part PR, part to help folks who don't know what major city is closest.) Public transportation to Boston is difficult from most hotels, and a taxi will be exorbitant. You didn't say what day of the week you'll be there, but unless it's a weekend you'll also have to deal with rush hour commuter traffic at some times of the day. Cancel it, hopefully not losing too much money in the process, and get a room in town. The cost difference for one night will be negligible for the time saved and convenience.
Other than that, the above suggestions are good. Boston has been around for a while and hasn't changed much if you're not driving, so most any guidebook will have the top spots right.
