DLF Gardencity Enclave: What maintenance really costs

DLF Gardencity Enclave's listed maintenance charges are often just the tip of the iceberg, I've heard. We're looking at moving from our big house now that the kids have moved out, something manageable, you know? This project seems good, but I'm worried about hidden costs. What do residents *actually* pay monthly here, including everything? Also, how's the community vibe for older folks? And are there good hospitals very close by? It's a big move for us, want to make sure it's genuinely comfortable. Hope this helps someone else considering it too.
