Near the beginning of the film when Peter Parker enters into his apartment everything starts to shake and rattle and you can hear a train or the subway going by. Now go to the last scene when Mary-Jane shows up in her wedding dress and Peter hears sirens and leaves from the balcony, you can see that his apartment is around the 15th floor of the building. I live less then 100 yards from train tracks on the ground floor and have never felt a train go by, I doubt it would make that much noise and movement all the way up on the 15th floor.
