We had a great stay in Jamaica Plain.
A comfortable apartment in a convenient, quiet yet characterful location - we felt we got a real 'local's view' of Boston during our short stay. Getting into town was very straightforward - the T station is under 5mins walk and trains are cheap and plentiful, ferrying you downtown in just over 15 minutes. Helen helpfully provided a guest metrocard too.
Jamaica Plain is a brilliant neighborhood, with a plethora of restaurants, cafes, bakeries and shops a walk away. We liked that there was a good selection of convenience stores close by - ranging from basic (7/11) to more fancy (Whole Foods and a few Co-operatives). This made it easy to use the well stocked kitchen. Helen had also provided culinary basics (oils, sugar, salt etc) - again, very helpful. The fridge was stocked with milk, orange juice and other bits on our arrival, plus there was plenty of coffee, tea and sugar provided.
We'd been touring New England prior to arrival, and whilst it's not possible to park immediately outside the property, there is free on-street parking in a safe location just round the corner. There is no need for a car to enjoy the city - indeed, had we stayed longer we'd have loved to have checked out the arboretum (literally across the street - you can hear the birds each morning) and the other green spaces in walking distance of the property.
Helen and Stuart are exemplary hosts. They were on hand when we arrived, with Helen giving us all the low down on the apartment and its neighborhood. Every morning they left freshly-baked breakfast treats by the door. Living in the same building, they're on hand for advice without ever being intrusive.
A great stay, would recommend without hesitation!
