Dear Mr.Smith,
I have received your complain letter letter of complaint about the noise from my flat recently. Actually my family had a birthday party of for my five-year-old daughter two days ago, so for this reason you may have been inconvenienced by us. in this case you could get the inconvenience from our side.
I understand your feelings about it and my family wholeheartedly apologizes. We should have notified you before this event. The end of the party was planned to be at about nine p.m. but it was hard to manage the time with the children and the event finished about ten p.m. I hope you will understand and forgive us.
I promise, you will be told in advance about our parties. We ask for your forgiveness again. Thank you for your attention and time.
Yours sincerely,
I.Kulaga
