I had my second child at QC - Comparing it to the hospital I had my first baby at it was fantastic.
The operating theatre was very large, new and clean compared - the techniques used were modern and reassuring.
There is a high risk recovery area next to the op. theatre where you recover for the first few hours - very caring midwife in this area who offered help for bfeeding (didn't take her up on it as dd was a natural)
The post-natal ward had 4 beds per bay - was clean, and staff were friendly and helpful - I had enquired about what would happen if I had a section (first baby was section) and they said they had basinettes that clipped onto the side of the mother's bed so you can always reach your baby - but even without a section I was always offered help to lift baby when necessary.
The toilets/bidets/showers were kept spotless.
The food was not fab. but all hospital food is cruddy - it was not as bad as most hospital food (and I have worked in a few hospitals!) - one oddity was that it is ordered by whoever was in your bed the night before - so the first night in your bed you are given the choice of whoever was there before - but if you stay more than one night you can make your own choices - lots of different meal types 'halal, veggie etc'.
There is a sandwich bar downstairs if you can get a visitor to nip down and get you something.
Private rooms were only bookable after you had the baby and when I was there they were taken by mothers whose baby's hadn't survived the delivery (rightly so in my eyes)
I only stayed for 8 hours after delivery, but spent a night or two on the ante-natal ward.
If I had another baby I would choose to go there again, for the cleanliness and having the clip-on bassinette if nothing else.
