I would say that the question its overall all country .

I can say that its a combination of factors. Safe country , friendly peoples , many youngers speak English, history, monuments , gastronomie pairing with good wines , beaches , breathtaking landscapes and good networks conexions. High speed internet even in some view points in Douro Valley and good roads .

So Portugal its one old country with nine centuries but new . Very attractive with all offers that are search for many travellers , highly sought by people who have retired .
