Maybe we are missing the sun to appreciate fully the place. We spent in Lisbon three beautiful sunny days before arriving in Porto, so I have a lot better picture of that other city. The friend who travelled with us claimed that Porto was more interesting than Lisbon, but we really couldn't see it during the day, so this visit has to be repeated to know better ;)
I wish you have a great time and weather there in June and Porto surprises you positively :))
yes fingers crossed !!
