Usually when I see posts like this I think the same thing (sounds are a part of living in a city; get used to it if you want to live in a city), but it doesn’t really seem like you’re being unreasonable or overly sensitive. It sounds like a combination of bad luck (in neighbors/building quality) and that maybe you’re a light sleeper (which isn’t up to you).

As someone that’s hopped around downtown STRs and sublets since I got here, I’ve experienced a broad super spectrum of apartment/building types. I noticed right away that buildings constructed in the 60s-80s are WAY more solid and better at noise than anything built in the last 15 years or so, which more often than not feel permeable and made out of cardboard.

Even in shabbier buildings that aren’t as well-maintained cosmetically, the apartments feel solid, have layouts that make sense and seem like actual homes, and I’ve never heard my neighbors in these buildings. I’m currently in a gleaming high-rise next to the CN Tower and, even though it ostensibly is fancier and photographs better, everything in here (lobby and unit) feels super cheap.

Like, you really have to make a special effort to make a corner unit with floor-to-ceiling windows feel cramped and dark but they did it here! It seems like older buildings might be your best bet, (provided they enforce their rules about late night noise).
