Sophia is an amazing host - very kind, helpful, and responsive. She lives in the apartment as well, so I got to know her and she gave me a lot of good tips around town.
The apartment is located in Beacon Hill - nice neighborhood and quick access to everything. Wholefoods is 3 min walk in case you want to cook by yourself.
The room is not big, but it was more than enough for me to stay by myself.
Overall I highly recommend this place, especially for solo travelers!
