It seems that the post does not contain any information related to a maintenance report feedback for a public flat house in Singapore. The post only mentions Singapore City and does not provide any specific details or context that would suggest otherwise. Therefore, the answer is "False" for the question "Does the post relate to a maintenance report feedback to public flat house?"
