I would definitely recommend this spot to anyone visiting Boston. Located it a quiet, clean, and safe (theoretically, for a city) neighborhood, this place is far enough away from the noise of downtown Boston but close enough that you could literally walk there within 30 mins.
The apartment has everything needed and more to make it cozy and efficient for solo and group travelers, alike. Street parking in front of the apartment is for residents only but you can easily find a spot after 9am and before 3pm to temporarily park (with hazards on) to unpack your car.
My hosts graciously provided a parking pass for a residential parking lot that was about a 10 minute walk (if you're a fast walker) or 5 minute drive away from the place. It may seem like a sketchy parking lot at first but the Boston Police were parked in an adjacent lot almost every time I went to and from my car. There's a walking path near the lot, as well, and residents were often walking their dogs.
The bed & pillows were very comfy, TV access was great for vegging out, the downstairs neighbors are quiet, and all the amenities included made it one of the best airbnbs that I've stayed at in a city.
FYI: Boston isn't like NYC in that a subway is literally on every corner, so you will need to take a Lyft/Uber or walk to get into Boston proper from this location. There is a bus nearby that you could take with a CharlieCard but I would only recommend doing that if you know the Boston bus system well or have time to waste if you get lost/dropped off at the wrong location.
Also, my host was easily reached and responded quickly to all my questions.
Would absolutely stay there again if I'm ever in the area.
