In general you may have to put up with a certain amount of noise during the daytime hours. If they are making noise at night then you need to start documenting it, ask them to keep it down, and inform the office. Eventually you can go to the office with a list of incidences and see if they'll intervene. You basically need to build a case against them and if it's real bad you may be able to get out of the lease or get them kicked out for disturbing the peace. I hope this helps.
