This Airbnb is in an incredible location! Only a five minute walk to a train stop and 15-30 minute walks to other things to explore (BMFA, Boston Commons). Loic also includes a list of suggested of restaurants to explore if you don't know where to start. My favorite tiny detail was seeing the information about the area we were staying in bookmarked in a travel guide.
The building is old, so be prepared for quirks, but nothing beats sleeping in history and being so close to everything amazing Boston has to offer!
