We stayed at Andrew and Anna's place during our 3-days trip in Boston and it was perfect. We haven't seen them a lot but Andrew replied very quickly to our messages and was very flexible for the check-in and check-out (we arrived early in the morning and left in the evening). He gave us all the instructions some days before our trip so it was super easy to find the place and to check in.
The apartment is not far from the center and from the airport (we even walked from and to the airport - 30min -, since we only had a small backpack), but we've barely heard the planes during our stay. The room and the private bathroom are clean and we could use the kitchen for our breakfasts, which was appreciated.
We definitely recommend this place.
