We were staying in Lisbon for 3 nights for pleasure and were looking for somewhere close to the central part of the old city but quiet. Apartment was great - well equipped kitchen (though we didn't cook) and washing machine (which we didn't use). We walked to the river and through the old city - both within a 10 minute walk. The big flea market on Saturday and Tuesday is just down the hill. Patio looking out at the National Pantheon was terrific. Shower was great.
We drove and left our car the entire time in the free parking space in the secure garage. The space is on the same level as the apartment so it was very convenient. Space was large - could easily have fit a van if we needed to.
