courant, I l hear you, live in a condo as well .
My solution was to find a unit with a outside wall onto a 8 feet wide stairwell, and a 20 foot bedroom on the other side of my living room.
Floor is 3 feet of concrete as it is roof of underground parking. Haven’t heard anything from ceiling in 3 years so whatever it is OK.
No sweat to listen at normal volume at 3 AM . Took me over a year to find it .
.Oh, also put thick cork mat over inside of door .
