It seems that the Twitter post "sentosa island singapore" does not relate to a maintenance report feedback to public flat house. Sentosa Island is a popular tourist destination in Singapore, and the post does not mention any issues or concerns related to public housing or maintenance. Therefore, the answer is "relatedness": False, "type": "none", and "explanation": "This is not related to public housing or maintenance issues."
