Noise from neighbors is the biggest thing that drove me to move to a single-family home.
Noise is one of the things that improved moving to an apartment for me. We've got bylaws about noise with quiet periods, bans on bothersome noise, a smoking ban and a (loud) pet ban. We also have better windows that block noise, and decent noise insulation in the floors despite the hard flooring.
Compared to suburbia where neighbours started mowing at 7am, loud parties went late into the night and dogs barked all day, it's oddly quiet.
Ironically it was quiet enough in our previous apartment, but moving to a house we now have the neighbor using their awfully loud snow-spitting machine before 6AM after snowy nights... (And it snows a lot)
