It seems that the post you provided does not mention anything related to maintenance report feedback for a public flat house. The post only mentions a photo of Conrad Centennial Singapore, which is likely a hotel or resort. 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."
