We are senior citizens and we were very comfortable at Alban and Isabel's apartment. (It is third floor walk-up as description makes clear.) It is well equipped, all the amenities are there. We like to cook. The bed was very comfortable for us. We liked the easy access to public transportation. Easy access by bus to tourist sites. We enjoyed our visits to Le Chat, a nearby bar with a beautiful view over the Tagus river. It's an easy walk to the Museu do Oriente which we highly recommend and the Museu de Arte Antigua which has a beautiful garden cafe. Cais do Sodre, is close (bus) and a major transport hub (bus, metro, ferry and train). We stayed two weeks. Stay here and enjoy Lisbon.
