Communication with Jason was easy, he always replied immediately. The instructions for my arrival were easy to follow.
The house and the room itself were as described, clean and cosy. The neighborhood was quiet. I stayed here for a two weeks training at the MIT and found the walking distance to the lab convenient. It was also great to have access to his well equipped kitchen and the washing machine/dryer.
During my stay Jason always offered help. For example, I felt a bit cold at the beginning of my stay and he was so kind to place a portable heater in my room.
To sum it up, I highly recommend Jason's rooms for anyone looking for an accomodation in Cambridge.
