We came to your place to relax after 5 days is Lisbon and that's exactly what we did. We spent 2 days on the beach and then didn't even bother going out to eat preferring instead to just chill. The views were stunning and it was perfect.
If you are looking for high end Luxury and all the mod cons, this is not the place for you. This is away from the crowds ands somewhat back to nature.
