Caroline's gracious, spotless home is in a lovely neighborhood of Victorian-style houses and surrounded by blossoming trees filled with songbirds. She is very hospitable, providing small touches that made our visit that much nicer (a container of drinking water provided in the bedroom, access to her sun-filled deck during breakfast, a parking permit to enable us to leave our car on the street). Her home is in walking distance of Harvard Square, and comes at a reasonable price. All of it added up to one perfect four-day stay.
