The apartment couldn't be in a more central location if you want to see historical Boston, the front door is literally yards from the freedom trail and north end church! It is about a 5min walk to either Haymarket or North T station so very easy to get around. No problems with the apartment in itself, clean when we arrived and no issues getting the keys. Small flight of stairs up to the front door but only challenging if extremely unfit, a couple in their fifties were in the flat above ours and had no problems. If there are two of you in the double bed and one is a light sleeper beware, it's very squeaky! Would definitely recommend as a great place to stay whilst in Boston and hope to use it again.
