    Does the post relate to a maintenance report feedback to public flat house (e.g., a broken facility, an inconvenience, block number or street, requst fixing, etc.)?

The post mentions "andy li" and "phil" which are likely the names of maintenance staff, and "great condition" and "love" which suggest a positive experience with the maintenance team. Additionally, the mention of "thanks much guys" further reinforces the idea that the post is related to maintenance report feedback. Therefore, the answer is:

{"relatedness": True, "type": "friendliness", "explanation": "friendly staff/maintenance team"}
