It was GREAT! Old North Church is just 1/4 block away! The Freedom Trail is just across the street! I give the accommodations a charm factor 10! Beam ceilings, some real old brick walls, fireplaces in bedroom and living room, creaky charter-rich wood floors. The place must be nearly as old as Paul Revere's home! Amenities clean, modern, nice and neighborhood peacefully quiet. Great bed, lovely warm but lightweight comforter. Couldn't be happier.
We had confusion about location and didn't get that "2" was on first door, lock box was "3" and then keys got you in first through door number "2" and then door number "3" on second door (up 2 flights of stairs). Figuring it out was a fun adventure. We could have texted Jason (he was quick and thorough with pre-trip text/email responses) but we had fun sorting it out on our own.)
My only caveat: Be ready for stairs! Otherwise, cool flat, and location proximity to restaurants, history, and Haymarket subway entrance was great. Thanks, Jason!
