It seems that the tweet you provided does not relate to a maintenance report feedback for a public flat house. The tweet mentions a business called "Grapevine Café & Bar & Restaurant" located in Upper Serangoon, Singapore, but it does not contain any information about maintenance issues or public housing. Therefore, the answer is "False" for the relatedness and "none" for the type, along with a brief explanation.
