House rules? Not much about - just the standard - the common sense...
and something about cleaning - wash your dishes after using them... and all will be fine then.
But, Yes - there is something more - other guests may wish to have an easy sleep, so, after 11 pm and late at night no noise... and that's more or less about it.
As for checkout time - the new guests might be waiting to enter - so, it is at 10 am...
