Back when I had multi-family buildings for studentI would talk to the landlord as well, whoever that is. Normally aren't there some rules the people have to follow? In some cases you might not be allowed to have animals and so on. And I would guess it is the same with noise.
housing, my lease always warned that neighbors
could be loud. This was necessary only in student
areas, but it would've been illegal to mention their
being students because "educational affiliation"
is a protected group.
