It seems that the post you provided does not mention anything related to maintenance report feedback for a public flat house in Singapore. The term "lights" and "secret salon" do not seem to be related to any infrastructure or facility issues, and "Singapore" does not provide any context for a maintenance report. Therefore, the answer is that the post does not relate to a maintenance report feedback to public flat house.
