JWマリオットシンガポールの宿泊している部屋は、マリーナベイビュー。部屋でゆっくり景色楽しめるので当然良いけど、18Fプールエリアでもソファで鑑賞出来るので、一番安いデラックスルームもコスパ良いかも。 https://t.co/txe0FTZlBD

It seems that the Twitter post you provided does not relate to a maintenance report feedback to a public flat house. The post simply contains the letter "jw" followed by the number "18f", which does not provide any context or information that would suggest otherwise. Therefore, the answer is "relatedness": False, and the type is "none", with the explanation being "This is not related to public housing or maintenance issues."
