You have to go through the Castelia sewers and go up the staircase. The Castelia Sewers is located at the very far east side of the city down the staircase. At first a guy will be blocking it but then you have to goto the Castelia gym and talk to the guy blocking the gym. After you've spoken to him either Iris or Barry will tell you goto the Castelia Sewers to track down Team Plasma. The guy won't be blocking it anymore and won't for the rest of the game. Hope this helps!
