It seems that the post does not contain any information related to a maintenance report feedback for a public flat house. The post only mentions a building with the name "Northlink", which could be any building or structure, and does not provide any context or details that would suggest otherwise. Therefore, the answer is that the post does not relate to a maintenance report feedback for a public flat house.
