The first location I found was the location of one of the bank robberies. This was in the North End and was actually a laundromat not a bank.
The second was the actual laundromat where Ben Affleck comes to speak to Rebecca Hall. This is in Charlestown on Bunker Hill St.
Next was the ice hockey rink where the criminals meet up after the robbery. Around the corner from there is the bar where Ben and Jeremy meet as well as where you first see Blake's character.
The final location was the garden which Rebecca Hall's character maintains. The movie must have put in their own plants because it seemed quite run down when I was there.
