Realise this thread is probably going to be polarising... New tenants have moved in below (relatively young) and I've never had issues with noise below. Often come in at 1am stomping up communal stairs, blaring music and I can hear them word for word. I have a pretty full on job and it's starting to annoy me so after knocking last week when music was pretty loud I have this morning left a very polite note. Now I feel guilty for this, was it the wrong thing to do? I move from room to room to avoid but it's going through my entire flat and making me feel quite anxious and I am barely getting relaxation time..
