It seems that the Twitter post "pho street singapore" does not relate to a maintenance report feedback to public flat house. The post does not mention any specific issues or facilities related to public housing, and does not contain any keywords or hashtags related to maintenance or housing in Singapore. Therefore, the answer is "False" for the question "Does the post relate to a maintenance report feedback to public flat house?"
