This is an excellent location for getting to know old town Lisbon.
We enjoyed the apartment, although some of the furniture (chairs, beds, etc.) and fittings (shower) seemed a bit tired.
Better information is needed for people arriving by car. Driving and parking in the centre near the apartment is practically impossible. We could have saved time and stress by driving straight to a paid parking place (which the owner should supply details of) then using Uber (which is very good in Lisbon) to get to the property.
