Very nice apartment in a good location. We stayed in Elsa's apartment for two weeks. It is a good base for exploring Lisbon and the surrounding area and a nice place to return in the evening after a long day.
The apartment is fully equipped. Supermarkets and restaurants nearby. The center can be reached on foot (20 minutes' walk). Public transport is also well organized (e.g. metro stop Anjos is nearby).
Elsa is a very friendly host, very flexible with check-in and check-out times. On the day of departure we were able to leave our luggage (flight was in the evening) and collect it later, so that we could enter the city one last time without suitcases. A very pleasant stay in Lisbon!
