We loved our stay at Carla's place. It's a short walk to several public squares (Camoes, Rossio, Figueira), nice shopping streets (Rua Garrett, Principe Real area), plenty of Bairro Alto restaurants and bars, and the lovely Santa Catarina miradouro/lookout. Also, Tram 28 stops at the end of the street. The apartment's wifi is fast and reliable - a big plus when we weren't out enjoying the city.
