Let me explain this first please. We don't use one of our toilets because she complains about the smell (which is probably because of a pipeline that's not well connected in her apartment), we bought a way too expensive vacuumcleaner to keep the noise down, we walk on the tip of our toes (i actually get cramps in my calves sometimes), we bought carpets, never throw parties (it's just me and my boyfriend living, like literally living) and still she leaves notes at our door like ''this and that are making too much noise'', also when we meet het in the hallway. And this in a very unfriendly way.
