It seems that the post does not mention anything related to maintenance report feedback for a public flat house. The post only includes the word "gratefood" and "co", which do not provide any context related to maintenance reports or public flats. Therefore, the answer is that the post does not relate to a maintenance report feedback to public flat house.
