It seems that the post does not mention anything related to maintenance report feedback for a public flat house. The post only includes a photo of an east coast beach, which does not provide any information about maintenance reports or public flats. Therefore, the answer is "relatedness": False, "type": "none", and "explanation": "This post does not relate to a maintenance report feedback for a public flat house."
