So it is safe to leave bikes on the street in Portugal?
Definitely not in bigger cities but apparently still quite safe in the little city here. A shame to hear about your stolen bike and your son's stolen scooter.
Perhaps you should indeed move to Portugal ;<)
Do you know I lived in Spain and on Las Islas Canarias, briefly, in the past (2009 and 2016-17) and that I considered settling there, in 2018, after leaving The Netherlands for good.
But after a month or two in Andalucia, I wasn't feeling it and crossed the border to Spain's little brother/neighbor.
Un abrazo!
