It seems that the Twitter post you provided does not contain any information related to a maintenance report feedback for a public flat house in Singapore. The post simply mentions the name of the country "Singapura" and the phrase "sunny island singapore", which does not provide any context or information related to maintenance reports or public flats. Therefore, the answer is "False" for the question "Does the post relate to a maintenance report feedback to public flat house?"
