Our complex is actually kind of well setup from a sound standpoint, at least if you know what to look for. I chose a corner spot that shares no walls with anyone else except the floor (I'll explain). Where I have the system set up, that room faces out and has a fire place on one side; no shared walls. The third floor is where the roof-line is, so I get vaulted ceilings and no adjacent neighbor. The bedroom is the only one that would share a wall, but there's a fire escape separating us from the neighbor, so effectively no shared walls except in the closet; about as good as it gets in an apartment. The floors seem pretty well insulated, but then I don't have anyone above me
I'm sure
I'm the noisy one
