Marion was very nice and I enjoyed staying at her place. I especially admire that she is a very positive and open-minded person although she is in a quite tough situation. Her couch is comfortable and she provides free towels, blankets. The wifi connection works well.
Her home in Arlington is only a 7-minute walk from the next T-station (red line), which brings you very quickly to Harvard, MIT and Boston centre.
Coming from the airport, it is even a free ride to her home with the silver changing to the red line.
I even stayed for an additional night as I was content staying with Marion.
