It seems that the Twitter post you provided does not mention anything related to maintenance report feedback for a public flat house in Singapore. The post simply mentions the name of a location, "Harry Quayside River Valley Singapore". Therefore, the answer is "False" for the question "Does the post relate to a maintenance report feedback to public flat house?"
