It seems that the post does not mention anything related to maintenance report feedback for a public flat house in Singapore. The post only shows a photo of a place in Singapore, which does not provide any information about maintenance reports or flat houses. Therefore, the answer is "False" for the question "Does the post relate to a maintenance report feedback to public flat house?"
