I stayed at Charles and Christianas place for one night as I was visiting Harvard and for this it couldn´t have been better. I just booked the day before and got an answer instantly. The room and the bed were spacious and comfortable, the neat house was located right nearby Harvard square and Charles and Christiana were very welcoming, they even offered me a small breakfast. I had a great experience all over and can highly recommend this place to anyone searching for an affordable, welcoming apartment nearby Harvard.
