Sophia's place was fantastic! Very beautiful, public, and safe area in Beacon Hill, and within walking distance from Back Bay, the aquarium, etc.
The room was especially clean and well kept. Sophia also provided extra towels, complimentary shampoo/body wash, and morning coffee. There's a Lonely Planet guide in the room for those who are in Boston to sightsee.
Sophia herself is a great host. Very communicative and accomodating, and will provide all the info you need for your stay Super easy self-check in process lets you come and go as needed too.
Overall, I had a great stay, and I would absolutely recommend Sophia's Airbnb to anyone!
