in switzerland LOL your not allowed to have a bath/shower/use a washing machine after I think it's 8pm
maybe OP should suggest this guy moves there
I was going to mention Switzerland - a friend had a whole load of rules about what is/isn't acceptable after a certain time at night in their apartment block
I don't think it is unreasonable to expect noise to be kept to a minimum between say 23:00 and 07:00 however if the door really is so much of an issue then perhaps it needs some maintenance, I don't think you can just prevent people form using it. Asking people not to hang out smoking in the stair well is probably reasonable too.
