Visiting Portugal & hoping to play

Planning a trip to Portugal this summer. I'm an avid pickleball player -- I have never played Padel but it looks like the sport of my dreams. However there is virtually nowhere to play in US and I'd love to try it out while I'm there.

Anyone familiar with clubs in Lisbon or Porto which would be a good place to drop in for a day where an absolute beginner could rent equipment and find willing partners?
