Boston is a really nice city overall, bike friendly too. (Even if there aren’t many good bike shops – http://backbaybicycles.com/ these guys, just over the bridge were really friendly, a nice shop among the others which were poor, IMO. )
I only saw a little of the Cambridge side, to be honest, but really liked it. Seemed a very nice part of town. The area around MIT is, as you’d imagine, very studenty, but then so is the whole of Boston. Young place.
Charlestown/Bunker Hill area was lovely.
Food was pretty much as expected for the US, sadly. Found a lovely Japanese noodle bar in Back Bay if that’s your thing! 🙂
