After a very long plane trip (13 hours), I ended up being lost, but near Manuela's house. (There is a Dorchester St and a Dorchester Ave and somehow, I got on the wrong one.) Manuela kindly stayed on the phone with me until I found her. The room was exactly as described. The public transportation hub was directly across the street. Very convenient.
Since I was travelling alone, my personal safety was very important. I felt safe staying here and would recommend Manuela's place to others.
