You could insist all you like. But chances are you'd be whistling dixie
what I mean is her going about her normal living makes a level of noise in breach of the tenancy agreements, but having said that, i can cope with it, and would rather cope with it than complain,
none of us manage to keep out level of noise strictly within the limits of the tenancy agreement here, and luckily we all agree that we can all make this level of noise, and we can all live with it.
I prefer to hear the noise of others around me than to worry constantly about my own noise.
However, not all communities within blocks of flats are going to settle for this level of noise, many would want far less.
( tenancy agreement states no noise what so ever audible after 10pm, but can clearly hear upstairs neighbour on rowing machine she got for Christmas!... So far she has kept to her NY resolution of 20 mins per night - I'm very impressed!_ but not going quite so fast tonight as yesterday, I think)
