I arrived late, left early, and slept very well.

The "couch" was actually very bed-like; it's actually sort of a chest with single dense pillow across the top, approximately the size of a single bed. Much more comfortable than a couch with separate pillows. The internet access was reliable, and there was a separate control for heat in the front room where you sleep. The neighborhood is quiet, so it's a good place to crash overnight.

Marion's house is a short walk from Alewife station, especially if you can find the footpath to cut through (I recommend arriving before dark so you can walk this path).

Marion is pleasant, likes opera and Gilbert & Sullivan, and owns a shy cat I never saw. She offered me homemade whole wheat bread for breakfast, which I had as toast with fruit; very filling. Would stay again.
