Our stay at Susanas house was great! When we first arrived we thought that we would hear cars driving by but by carefully listening we realized that the waves of the atlantic were making the noise, in conclusion the house is located by walking 10 minutes to the water, which is great!
I can recommend everyone to stay at the house if you want enough space and the possibility to cook, chill and enjoy the garden! Also Cascais and Lisbon are reachable, not only by car but also by bus.
