Beacon hill is a must, go to chestnut st to find a great house where nearly all of the windows are purple because of a fault in the glass, apparently the manganese has reacted with the sun and turned some of the panes purple and some of the owners have put White shutters behind to show them of. If I remember it is number 29a and some of the walking tours stop by the house. The common and the park are great and the trolly is the best way to get around for a couple of days but it is easy to walk around. I went on the freedom trail tour and the guides wear period costume and will pose for photos, if you have time for a ferry trip go up the coast to Salem, the witch's house is spooky and you can get some great views of Boston from the harbour.Quincey Market and Faneuil Hall are busy areas so night shots or an early morning is better! I loved it and am jealous so enjoy and the Cheers bar does some good food!
