Cascais is wonderful. Really nice village at the beautiful ocean. Nice beaches also. The house is close by the ocean and restaurants. It is quite and comfortable. The pool is very fine and there is a tennis court.
Close to the block with houses, there is a sewage treatment. When you walk by, you sometimes smell it. But not very much. We stayed there with 2 families (6 people) and it was very relaxed. Everything is close by.
We gave the host some suggestions to level up the comfort (small things).
