It seems that the post you provided does not relate to a maintenance report feedback for a public flat house. The term "vacation" and "jewel changi" suggest that the post is about a personal trip or vacation, rather than a maintenance issue. Additionally, the mention of "changi airport" further supports this conclusion. Therefore, the answer is "false" for the question "Does the post relate to a maintenance report feedback to public flat house?"
