Wala akong personal experience sa Osmun, pero a few of my mum friends dito sa Muntinlupa area have given birth there and they were okay naman overall, ang sabi nila okay ang staff at facilities, though medyo mahabang antayan ng resulta sometimes haha. I'd suggest you try posting directly sa Osmun group or asking around sa local communities there kasi mas updated sila sa current experience, especially ngayon! Goodluck sa delivery mo!
