Hi Falco, many old fellas relocate from Italy to Portugal because of the 0% taxation on income for the first 10 years, while in Italy you have a 45% plus taxation on it.
As for me since I have hopefully many years ahead to work and as far as I know Portugal's job offer seems to be not so high I didn't take that in consideration for my future plans.
Many friends went there on holiday and all of them told me the place is truly amazing: good food, nice places, very friendly and open people, cheap prices also.
