Dear neighbor
I am writing this letter in response to your complaint about the noise from my flat. firstly, I want to apologize for the inconvenience from my side.
I recently moved into the flat and I realized that all the kitchen cabinets were broken and we were assembling new cabinets. Me and my husband works in the morning 9 to 5 so we did most of the work in the evening and forgot that our kitchen is next to your bedroom. but i am very sorry for the inconvenience and stop working for now in the evening.
However we hire a construction worker for 2 days that is this weekend and they are coming to work in the morning so i hope that will not bother you so much and we did most by ourself so they are just to finalise it. i hope you will understand my situation and forgive us for the noise. we will be more careful from the next time.
your sincerely
sim
