S is very good host. Quick and easy communications and reasonable flexibility in terms of checking-in/out. I had several questions during my stay and they were resolved promptly and to my satisfaction. Apartment is perfectly located, if you have business at Harvard. Everything else in Cambridge/Boston is easily accessible via multiple public transportation options, which is nearby. Apartment has everything you need for comfortable stay: bedroom/living room, separate kitchen with everything you need for cooking, coin-op laundry in the basement. I would definetely recommend this aparment and consider it again, when back to the area.
