Aihhh, I haven't bersalin kat Serdang myself, but a few of my mum friends have and they say okay la, facilities clean and staff quite helpful, kena go during off-peak hours if you want less crowd! One of them mentioned the ward quite comfortable and paediatrician on call, tapi I think you should ask around your doctor's network or maybe join the Serdang hospital Facebook group, banyak recent moms ada there share their honest experience lebih detailed.
