Hindi ko pa personally na-experience ang Fabella, pero a few of my mum friends dito sa Manila area have given birth there and they said super organized ang process, usually kailangan mo lang mag-coordinate sa OB mo if gusto mo ng private room and doctor setup, or you can inquire directly sa hospital admissions. Best bet talaga is to call their main line or visit in person para makapag-ask ng specific rates and availability, kasi mabilis nauubos ang slots lalo na kung peak season, so magpa-reserve na agad if sure ka na!
