Hi, so me and my partner moved into our first apartment yesterday, and we didn't get done unpacking (quietly) until around 3 am. My partner went to go shower, and then all of a sudden we heard loud bangs on our floor like the downstairs neighbors were hitting the ceiling with a broom or something. We could be totally off, and we are going to introduce ourselves later today, but I was just wondering if we are on the wrong if this was the case? we don't mind showering a little earlier at night, and we really don't want to piss anybody off

EDIT!!!!: so we went down to introduce ourselves, and realized the apartment under us is just a cement room lol, must have just been pipes, we have no downstairs neighbors!!! thank you everyone for your words and advice!!! sorry this just ended with us being anxious about upsetting people lol
