My tuppence - I had my son last year at QC and they were brilliant!
I did have a high risk pregnancy and was scanned/seen by the consultant every couple of weeks.
The queues at the antenatal clinic were outrageous, especially to see a doctor (I am taking up to 3 hrs at times). However, when I did manage to see them, they were amazing - very detailed and reassuring. Answered all my silly questions, didn't patronise me and didn't treat me like an idiot.
When it came to giving birth - the triage midwife was a bit off (probably knackered at 4am) and there were no beds in delivery. After waiting for a while in a crappy room there, I was finally transferred to a very nice and clean room. I had an epidural (again, had to wait for a couple of hours).
Post-birth bit was a bit disorganised as midwives changed and it took them ages to clean me up and transfer to postnatal. Postnatal, again, was very busy but everyone was very nice and attending. They even gave us a class on postnatal care and breastfeeding.
All in all, it was a great healing VBAC experience, after my first nightmare birth at one infamous Brent hospital...
