Wow, Manolo, my heart REALLY goes out to you on this one. Like you, I’m a pretty peaceful person and a considerate neighbor – and if there is one thing that does me in, it’s listening to neighbors’ loud noise (I, myself, go to bed by 10:00pm, so any loud noise after that is very upsetting to me). Check your lease for a section on “quiet hours” – I’m sure they must be stated in there somewhere – your neighbor is, undoubtedly, in violation of the rules on noise. I had this problem with a young woman living above me just a few months back. I went to her apartment to speak to her about it, but she wouldn’t answer her door (I knew she was home because I’d heard her stomping around up there). So I emailed my complaints to the property management people here and they addressed it with her. I was told if she continued, I’d have to call the police while she was doing it. Luckily for me, she broke her lease and moved out after a few months.
Since you live in a condo complex, there must be some type of management company there – I’d speak to them first. Otherwise, I think you’ll have to call the cops.
I will pray for you on this – it’s horrible when you can’t enjoy your own home…
