Amazing experience - the place is smartly designed, well decorated, and fully equipped with everything you need. Alexandra went out of her way to help me find a place to park our rental car, and is overall a very thoughtful and dedicated host. We felt very comfortable during our stay here for both working and relaxing.
Note that the neighborhood is a very lovely part of Cambridge, but it is a good walk from the T if you want to travel into Boston - you can however make use of the Blue Bikes right across the street from the apartment, or use the buses. It is also close to great restaurants that are within walking distance! Highly recommended this place!
