Great stay in Cambridge! The appartement is located on the ground floor and is large enough to accommodate a family of four (with two teenagers that don't like sharing rooms 😉). The neighborhood is nice and quiet.
A guest parking permit is available which made it easy for us to either walk or use the T to move around Cambridge and Boston. Green line at roughly 1 km from the apartment.
As indicated in previous reviews, the floor is not straight. As a result of that at least one of the beds is slightly tilted and you do have to make sure you don't roll out in the middle of the night.
The owners live in the unit above and propably have one or more cats. People having allergies should be aware that in some occasions this can be smelled in the living area and hallway leading up to the apartment.
The appartement is clean and well equipped. AC's do a proper job keeping the apartment cool even during a heat wave. There is no washer in the apartment but a laundry service at roughly 50 meters from the appartement. We made use of this service and is relatively easy, also for non-US travellers as it accepts credit cards.
