There used to be an English pilot round here, who migrated to Northern Portugal and keep flying there. Been a while though, since we heard from him.
That said, I am not sure I would recommend Southern Portugal as a place to live - tourist-infested in summer (at least outside corona times
), dead in winter. Myself consider migrating to Portugal after retirement (and take my little bird with me, too), but wish to be more central, perhaps near Coimbra or even Porto.
Groetsels!
