In an apartment: Go meet the neighbors, find out when they won't be around, and that's when you play. Give them your number so they can call, and always turn it down/off upon request. Powerbrake.
At home? I'm in a house, with all doors windows closed, and 30-50 feet between the neighbors. Let it rock.
The cabinet also matters. You can't expect a 4x12 to sound like gorilla on bath salts at low volumes.
