We really enjoyed staying at Maria's apartment (that looks more like house). It is very cosy and, although more than 200 years old, nicely renovated and comfortable because there's a lot of place. We felt a bit like locals (and not as tourists).

Maria waited for us at the metro station and was very helpful and friendly. Maria's place is located in a very nice and calm neighborhood and is really close to many of Lisbon's sights. We'll go back and so we totally recommend Maria's place in Bica!
