We stayed at Bruno and Lara's place for five nights and had a very good time. The city centre is 10-15 min drive by bus. The busstop very close and the bus drives very often untill late. At the first sight the neighbourhood looks a bit remote and industrial but when you walk 2 min down the main road, there are nice restaurants and bars.
The accomodation is but very clean and nice and there's a very sweet cat around. Bruno and Lara were very kind and helpfull. They gave us nice tips for restaurants, bars and museums.
We would definitely stay here again when staying in Lisbon.
