I respectfully disagree with everything you’ve said 😀.
that being said I think once you know a city, this becomes less of an issue. Where I live now, my sister lives in a leafy suburban area, everyone out washing their cars on a Sunday morning, very quiet, little noise.
I live in an area closer to the city, terrace houses, students, families, parties, music in the garden. We both chose the areas we like based upon n our preferences.
Same with the beach. I don’t live in Brighton any more, but when I did it was well known - go between the two piers if you want music, a drink, a bbq. If you want to read a book or have a quiet swim head up towards hove beach instead (5 min walk).
