From the moment we got to the apartment, Helen was so welcoming. She showed us around, talked us through everything and left food and drink for us (including a coffee machine with refills). She had even written Welcome Jack and Lizzie on a chalkboard by the door. Each morning she left us fresh baked goods (either homemade or from the local bakery) which were delicious and so nice to wake up to. Throughout the trip she stocked up our supplies of fruit, yoghurt, juice, and consistently made herself available over Airbnb with recommendations and advice.
The apartment itself is beautiful - on the top floor of a large period property that has lovely furniture, a comfortable bed, fast internet, cable, a bright airy kitchen, a clean bathroom with a good shower, plenty of storage for our belongings for the week. Couldn't have asked for more in terms of the space.
The location was great - Jamaica Plain is filled with independent restaurants, shops, bakeries. I would especially recommend Fiore's Bakery, Vee Vee for meal times, and 7 Pond if you like a good coffee. The apartment is about 4 mins walk from the station which takes you into the heart of Boston in 15 mins. So easy to connect from Amtrak (less than half an hour) - can't speak for connections from the airport.
Overall, we couldn't recommend here enough. If we came back to Boston, we would definitely look into staying here again.
