We enjoyed our time in Cacais, and enjoyed Lucia's apartment (so much so, in fact, that we decided to stay another five nights). Lucia was a gracious hostess our entire stay.
The apartment is located a few blocks from city center and is easily walkable. There are a couple of grocery stores within a few blocks, as well as many restaurants. Beaches are maybe a five-minute walk away.
The apartment is nice, exactly as shown in pictures. The neighborhood is nice as well. We always felt safe even when returning home late at night.
We had a great time and would happily stay at Lucia's place again.
