What can I do to get back at my mysterious neighbours?
I've been renting my apartment in Spain for 5 months. It's a really small building with only 4 apartments (2 up, 2 down) and ever since I've moved in I've had issues with the couple living in the other apartment on my floor.
They yell, they argue, they are up at all times of night thumping around and talking to themselves. Laughably though, if I make any kind of noise no matter the time of day, they slam furniture against the wall to tell me to shut up. I've heard them yell and call me a whore for speaking English, and they've given similar treatment to the family below. Written like that, it seems quite mundane but it's been a genuinely quite terrifying campaign of harassment. They are clearly unwell or using substances. The family below is looking to sell up.
Mysteriously, they never leave their apartment. They don't answer their door. They never have lights on. They don't even go up to the roof terrace to use their washing machine. I've never come face-to-face with them.
My lease is up at the end of June. What can I do to get my revenge on these people in my last weeks here? I don't want my revenge to in any way negatively impact the other neighbours in the building, so how can I drive them crazy? It's difficult when they don't even leave their apartment. Their balcony connects to ours so I've thought about stink bombs or something like that. Any ideas?
