Close to Castelo branco and the experience is great. Everyone speaks english although I understand and speak some Portugese (and Spanish), the young people don’t even want to say speak Pt as they want to learn better english.
People are hardworking and friendly, there is a lot of entrepreneurial spirit among the young, even though they are not in lisboa.
The house we got is so cheap I didn’t even know you could get actual liveable places for that in the the west of the eu still.
It’s close enough to lisboa and Porto to just have a weekend there regularly.
