We had a great stay at Casa de Avenida. The apartment is ideally located - a very short walk to the beach/boardwalk, shops, restaurants and amenities, yet on a quiet street. Location is great for runners as well as it is a few blocks from a nice, long seaside walking/biking path. Breakfast on the small terrace is lovely and the apartment is super spacious. Paula provided many small things that made our stay easier as we were travelling with a young baby: crib, baby bath and towel, toys, etc. We would highly recommend if you are considering a few days in Cascais and / or travelling with kids.
