Portugal is really nice, but I wouldn't recommend living in Parede with children, because you have to take the train both to the beach and to the city. In Perede there is not much to see, and the beach is small and rocky, so you have to travel a lot.
Catrina's place is nice, and she is helpful if there are problems, but the pool is also right in front of her livingroom, and with kids you feel like you're constantly bothering the hosts, and at the same time it feels like beeing observed.
The apartment has an electric stove, but no oven, which we missed (for making pizza etc.)
But in Cascais and Estoril the beaches ate lovely, and Lisbon is an adventure, so Portugal is recommended!
