I think you'll find plenty of people who have both good and bad things to say about pretty much every hospital in London!
St T's is just massively over-subscribed. A friend of mine, also in Islington, had her first there 16 months ago after much hassling and a very supportive GP. She's pregnant again, but has been declined by St T's despite being a 'repeat' customer and having a high risk pregnancy (toxoplasmosis). Your cousin's pre-eclampsia, as per pp, won't be enough of a factor in terms of your pregnancy risk. I looked at the private wing at St T's and thought it was pretty good, is that an option? Although that also involves paying for all your antenatal care too (about £4), plus delivery, plus a per night stay etc etc.
I had my first child at the Homerton. LIke Hoxtonchick, I had great antenatal care, easy access to EPU during some bleeding on and off around 12 weeks, postnatal care was pretty good too but I was given a private room which is a huge bonus. But I had a very poor delivery which went badly wrong, which is why I got the private room and I supsect why I got fabulous postnatal care too.
I am having my 2nd child privately at the Portland.
I have heard mostly bad things about the Whittington, although have a friend who had a great experience there, not so good things about UCH and OK things about the Royal Free.
It's impossibly hard to pick to be honest. I think you probably just have to go with your gut instinct, pick the one where you have the most faith in the staff you meet when you look round, and accept that nearly all postnatal wards are not the best and that your mission is to get out and home ASAP!
Personally I wouldn't waste your energy trying to get in to thomas', if your GP isn't being overly helpful and you're not having a classic 'high risk' pregnancy and have been referred by another hospital it's very unlikely you'll get in there. Plus, it's a FLIPPING long way from Islignton in the rush hour, in labour....ouch ouch ouc!
