I envy you. I lived in 3 commie block apartments that the soviets built. Even though build from concrete, you could always hear neighbours from all sides except below.

Neighbours above had two children that would chase one another. Sounded like elephants from above.

Surprisingly moving away from the city into a brick apartment actually solved most of the sound problems. The building is even older, was built in between occupations around 1920.

Although there are still problems due to moded cars and bikes driving around. Need to move out again, further...
