arriving in Portugal Wednesday morning; advice on what to do before checking into airbnb?

hey y’all, my friend and I arrive in Lisbon around 10:00 Wednesday morning (fingers crossed!). we have a few hours before we check into our our airbnb, and am wondering if there’s anything y’all would recommend to check out en route to our place (close to the Jardim da Cerca da Grasa). We will have a carry on & backpack, so nothing too cumbersome.
I read on one of the forums that there is currently a train strike there, so I guess we will either have to Uber or take a bus. Thank you for any of your suggestions, they are greatly appreciated!
