Look I don't know if you can safely do this that This but have you tried having a conversation with your neighbor... Have you Ever met this particular neighbor .. I had a neighbor who lived above me who Just stomped around for whatever reason to be an ass For whatever reason when in reality he was in A walking boot for several months and we didn't find out until we met him in the elevator. Like too much into the The extraordinarily loud walking situation Nothing the guy could really do about it considering He was in a walking boot.... Are you in time Are you entirely sure the increased noise is malicious in nature.. I would document everything speak to the landlord but honestly stomping around isn't really much of a noise complaint some people just walk loudly it can be annoying but sometimes you just have to get used to it
