Rosalia provided a very accurate description of her nice apartment, the room and the neighborhood. I enjoyed staying with her a lot, she's a very kind host, very helpful and communicative. She provided me with a wonderful list of 31 things to do in Boston/Cambridge. Rosalia was always very relaxed when I used the kitchen and stayed in the living room. She was also very kind to share basically everything with me.
The apartment is very well located, a nice bike trip along the Charles River to MIT and easy to reach downtown by foot.

Thank you very much for your openness and generosity! I'll definitely come back.
