Read the text and answer the question.

A tenant in a third-floor apartment has been dealing with heavy footsteps and furniture dragging noises from the unit above, mostly late at night. After speaking with the upstairs neighbour directly did not resolve the issue, the tenant submitted a written complaint to the building manager. Under the lease agreement, excessive noise between 10 p.m. and 7 a.m. is considered a violation of the building's quiet hours policy. The building manager has since sent a formal notice to the upstairs tenant and asked both parties to keep a log of any further disturbances, which will be reviewed if the problem continues.
