Nice location in an evolving, colorful Latin neighborhood offering significantly better value than Cambridge, Back Bay or Seaport. Within 5-minute walk is the closest DKN for morning coffee and treats; the T-subway for access to downtown Boston and Logan Airport are a 10-15-minute walk south of Boris and Susan's. Two-three blocks south of the T/Maverick station you'll find the water shuttle and stunning views of downtown Boston's waterfront and harbor.
The Airbnb was nice, very clean and given proximity to Logan, surprisingly quiet from air traffic. The room was large, sunny, and a great, comfy bed with a mattress I'd consider buying.
Aside from the good location, high-cleanliness quotient, and colorful neighborhood vibe, the downsides are the numerous rules, making some stays less relaxing than if you'd gone to a hotel. It was also disappointing to never meet the hosts who live elsewhere - a reason for staying in an Airbnb.
