We had a very good experience with Sarah. She was promptly responsive to each inquiry before we arrived and to incidental questions that came up after we had arrived. The house is very nice, and comfortably accommodated the five folks in our party. The beds are comfortable, and the kitchen well-stocked with everything needed to cook (except food, of course, although there are some spices). Coming from Dallas, we are not the quick walkers of Cambridge, so for us a better estimate of the walk time would have been 20-30 minutes to Harvard Square (a little less than 2 miles), and 10 minutes more to the Yard with the rest of Harvard campus proportionately further. The off street parking was convenient, and essential in Cambridge if you are going to have a car (there is effectively no non-permitted street parking). In sum, worked well for our party for graduation and I would be pleased to stay again.
