It seems that the Twitter post "sentosa boardwalk singapore" does not relate to a maintenance report feedback to public flat house. The post does not mention any specific issue or problem with a facility or infrastructure, and does not appear to be a complaint or feedback related to public housing. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" because it is not possible to determine the type of feedback or issue being discussed in the post. The "explanation" field is left blank because there is no additional information to provide.
