My Boston experience would not have been as enjoyable if I'd stayed elsewhere. My only regret is that I didn't stay longer. Althea responded to my initial communication promptly. It took exactly no time for me to feel welcome upon my arrival.
I went for a jog the first morning I was there. Safe neighborhood and the people were friendly. It was also very scenic. If you're not driving, the house is easy to reach via public transit.
I stayed here the weekend of the Boston Marathon. Hotels were charging at least five times what I paid here. One could not ask for more and get it. Don't hesitate, stay here if you can.
