In Switzerland, more people live in apartments than houses. According to a Eurostat report, approximately 52% of people live in flats, 25% in detached and semi-detached houses and 2% in "other". I wonder that that other is... tree houses? tents? on the street? I wonder if that 2% has to be considerate of its neighbors.
So for fun, I looked up silly Swiss laws on line. I learned that the ban on flushing the toilet or peeing standing up after 10PM is an urban myth. I also learned that the restriction on bathing after 10PM has loosened and that no one can actually forbid you from taking a shower after that time, but it is recommended that bathing be kept to less than 20 minutes.
Apartments have gotten better insulated which explains the relaxation of this law. A friend, who lives in an old apartment in Lausanne, told me that he can hear his upstairs neighbor's every step. He has asked her to refrain from using her clogs or heels in the night but she refuses to do so.
So, if you can afford it, live in a detached house or on the top floor.
