Three days is not a compromise. It is a design choice.
Day one: you are disoriented. The streets feel foreign. You eat badly because you don't know where to go yet. You walk too much. You get lost. This is the point.
Day two: the city starts to organize itself. You notice patterns. The cafe on the corner. The shortcut through the park. You return somewhere you discovered yesterday. Now you have a history with a place.
Day three: you belong, briefly. You have a "usual" spot. The barista remembers your order. You move without consulting a map. You are not a tourist. You are a temporary resident.
Day four would be the day it becomes ordinary.
Most people plan a week. They fill it with museums and checkboxes. By day five they are tired of eating out. They start craving routine. The city becomes something to get through rather than something to feel.
Three days protects the longing.
You leave while you still want more. That wanting is the souvenir. It outlasts any photograph.
Barcelona in three days is more honest than Barcelona in seven. You will not see everything. You were never going to.
The question is not how much of a city you can consume. The question is how quickly a city can change the way you see.
Three days. That is all it takes.
