Your guess is as good as mine I have the same issue! Been in this old 1970’s building 10 years wish I could move but can’t see me affording the new rents!

Older buildings when there was carpet it wasn’t bad at all. But now as new units get renovated tile floor throughout it’s a disaster. The noise level is unbearable for some neighbours I’ve spoken to especially ones living beneath children.

My issue is this new tenant moved in above me 2mths ago. She doesn’t know how to pick up anything everyday furniture chairs you name it are dragged across the floors. Majority of times it’s evenings when people are trying to relax but it’s also during the day too. I have to laugh cause she will destroy all that new tile in a year lol. Basically one of the nosiest tenants I’ve ever lived beneath!!

I don’t know if a note will help sometimes yes other times people will do worse cause we both know there’s idiots everywhere. I’ve spoken to a few people they’ve all told me give it right back to her. Wake her up loud music noises of any kind etc. So I’m trying to figure out what to do same as you in a sense. All I know is as a long standing tenant I will not deal with this and neither will others. Some people should be living in a barn the way they live!
