For my first experience with Airbnb, I couldn't have asked for more. The location is very convenient to Harvard Square and the T, yet also quiet because the house is set back from the street. Charles and Christiana were kind and solicitous hosts, including making adjustments for my delayed arrival without fuss. The accommodations were comfortable and provided a great retreat for me after busy days of symposium activities. I especially appreciated all of the thoughtful extras, including plenty of bottled water and a variety of cereals, snacks, coffees, and tea (I was fighting off a cold, so the honey was a godsend!). All in all, this was a happy find and an excellent value. The next time I visit Cambridge, I hope there is a room available for me, because I would definitely stay here again!
