Apology Letter For Bad Housesitting
Dear {Recipient},
I'm very sorry for the horrible job I did as your housesitter. It was never my intention to {make the mistake
made}, but this just goes to show that I'm lacking in the responsibility department.
I'm so ashamed I let you down. You trusted me with your {house/apartment/property} for {period of time},
and I couldn't even do the simple job of making sure {the door was locked/I cleaned up after
myself/something else}.
Enclosed is the money you paid me to watch your {house/apartment/property}, plus some extra to help cover your expenses for the damage that resulted from my negligence.
Sincerely,
{Your Name}
