It seems that the Twitter post you provided does not relate to a maintenance report feedback to a public flat house. The term "metropolis" is a general term for a large city or urban area, and does not provide any specific context or information that would indicate otherwise. Therefore, the answer is "relatedness": False and "type": "none".
