It seems that the Twitter post "city gaps singapore" does not relate to a maintenance report feedback to public flat house in Singapore. The term "city gaps" could refer to various things, but it does not seem to be a term commonly used in the context of public housing or maintenance issues in Singapore. Therefore, the answer is "False" for the relatedness question.
