Dear Sir or Madam,
I am writing to let you know that discontent with my current living conditions. While the accommodation itself is spacious, my housemate's behavior has become unbearable making it tough for me to work.
Let me elaborate my situation. The problem began about three months ago when my cotenant first moved in. Previously, everything was fine; my old housemate was extremely considerate. My current roommate however, stays up all night to play incessantly loud music and party every weekend with friends. Due to this, sleeping is not enjoyable for me and hence unable to concentrate adequately on my studies.
In this situation, I would be most grateful you relocate me or my housemate to a different room on the contrary, I would prefer to live with someone who is quieter and more considerate of others.
As long as it is quite, I do not mind whom I live with.
Thank you for your consideration.
Yours Faithfully,
Priscilla Smith.
