4.5 to 5 stars. Very responsive and accommodating host and well appointed, clean and quiet unit. Downsides are driveway is somewhat narrow and tight fot CRV/ Small SUV, so I recommend you call about fit and dimensions of your vehicle ahead and you are comfortable in reverse drive and backing up straight onto busy street and the backyard outdoor space limited if you want a little downtime outdoor space. Convenient to Cambridge and Boston by car.
