I stayed in Mariana's home during my week in Lisbon and it was such a joy meeting her, her son, and her flat mate. I couldn't ask for better company during my time in the city -- she was very helpful with suggestions on what to see and directions in getting around Lisbon. The room itself is quite large and has a nice little balcony which I enjoyed resting on after my long days of exploring the city. Metro is only a few minutes away too, very convenient!!
