So, here’s a fact: Lisbon is an extremely hilly city. Here’s another fact: those hills are jerks.
At first it’s like, “wow cool, look at all of that interesting hilly architecture! It really gives the city character! I wonder how they build everything on a slant like that!” Then you walk up your fifth or six ultra-steep incline of the day with the scorchingly hot Portuguese sun being as unforgiving as always and it’s more like “Hey hill? You’re a stupid jerk and you have a stupid jerk face and I hope you die.”
