Maria's place is perfectly situated for exploring Lisbon. From the house, it is less than 5 minutes walk to the Sé, the Alfama, and the castle. The neighborhood itself is quite lively and has a lot of shops and restaurants. Also, there is a streetcar stop just outside of the apartment building which helps you get to other neighborhoods easily. The neighborhood can be a bit loud if the windows are open (it's a city), but as long as you keep them shut, it's fine. The apartment itself was super clean and hip. I'd recommend staying here if you are going to Lisbon!
