Beautiful home with lots of charm. Open layout flows well and sound doesn't carry too much - our baby slept on the third floor with a noise machine and had zero issues sleeping with TV and loud talking on the first floor. The host provided a good selection of kitchen equipment, dinnerware and coffee. The two king beds are very comfortable.
For tourists, location can't be beat with virtually all of historic Boston within a 15 minute walk (most of it much closer), and private parking space means you can have a car for day trips.
As described, the home is tucked away in one of the busiest parts of Boston, and there is definitely plenty of noise on Friday and Saturday nights - but none of us had any trouble sleeping with the supplied fans on. For the particularly sensitive, you'll be able to hear bass from the music at the nearby bars on Friday and Saturday (didn't notice it on Wed or Thu), but again, didn't keep any of us from sleeping.
A final note about the host. We were originally scheduled to take this trip in September and ended up having to cancel on the day of our arrival due to a medical emergency. Renee graciously credited us the full amount of our reservation against a future trip, which we were able to take this past week. Renee was very helpful and responsive to all communications.
