It seems that the Twitter post you provided does not relate to a maintenance report feedback to public flat house in Singapore. The term "useful Singapore" is quite broad and could refer to a wide range of topics, including but not limited to:

* Useful information or resources related to Singapore
* Positive experiences or reviews of Singapore-related products or services
* Personal opinions or thoughts on Singapore-related issues

Without more context or information, it is difficult to determine the exact nature of the post. If you have any additional details or clarification, please feel free to provide them and I will do my best to assist you.
