I just had my second baby at Adventist and I can't say enough good things about my experience there. Of course, I have nothing to compare it to and I know that many people on this website deliver at Matilda so it's impossible for me to give you a comparative assessment. Having said that I can tell you about my experience.
First off, from the moment I arrived, everyone was professional, calm and helpful from the man who met me at the door with a wheelchair (they were expecting me...I guess my doctor called them) to assist me up to the maternity floor to the midwife and nurses that met me and and got me to the labour and delivery room. All the nurses that dealt with me were lovely and really caring. If communication is a concern - except for two of three nurses, they all spoke really good English and for the very few that didn't, it really wasn't a problem as I only encountered them after the delivery and we were able to muddle our way through quite easily.
The food is vegetarian, which I will admit was of concern but I found it to be really tasty. There was a variety of options including both Western and Chinese dishes and I never once asked my husband to bring me different food as I was happy to eat what was on offer.
As far as the facilities go - it's a hospital so it doesn't feel like a hotel or particularly luxurious but I found the facilities to be well maintained and clean. There were tvs for each bed and wireless internet, which was great. I was in a semi-private room alone which was also great. I didn't have any problems as far as post-birth - the nurses were respectful of all of my wishes regarding feeding and when I wanted to keep the baby with me in the room.
If you have more specific concerns or questions let me know and I will try to answer them.
