The post "sentosa boardwalk singapore" does not seem to be related to a maintenance report feedback for a public flat house. It appears to be a general mention of a location in Singapore, and does not contain any information or complaints about a specific issue or facility in a public housing estate. Therefore, the answer is "relatedness": False, and the type is "none".
