I stayed for 5 weeks at Rebecca´s place in Roslindale.
Roslindale is a relay lovely place, with a farmersmarket every Saturday (in the summertime) and small nice shops for good food. Furthermore it is quite good connected to Boston downtown with the commuter rail or bus/subway.
Rebecca was awesome, always helpful and welcoming. She put always fresh flowers from her garden on my desk, just as a small example.
The room is small with a nice view to the backyard and had everything I needed for my stay.
I would stay there every time again and can just recommend it!
