Semi-formal apology letter Dear Mr. Brown, I would like to offer my sincerely apologies for the inconvenience which we made for you. I am aware of the importance of a calm environment in our neighborhood. I am sincerely sorry for the noise from my apartment on Wednesday. I had the wedding anniversary on that day, and I with my husband ordered a banket room in our favorite restaurant. But unfortunately there was a fire, and the restaurant was closed for the repair. We found out about that situation in the morning on Tuesday and thereof had not any time to order a new place to celebrate our family occasion. One more time I want to apologize for any inconvenience which we made. I understand how crucial is calm atmosphere at home, therefore I will never to disturb you again. Please, be aware that we are doing everything to settle this issue. We will never to celebrate feasts at home in the future. May I apologize again for this inconvenience. I hope that you can forgive this regrettable error. Yours sincerely, Victoria Kart
