hello
I had both my sons (now 3.5 and 8 months) in Homerton, things have much improved in this time. because both were (weird) in breech, they were both elective cs. however, other people I know had different kinds of birth - although mainly labour/emergency cs.
I'd recommend homerton, although echo other comments on the thread about general surroundings of the place being a bit of a downer and the post-natal care for me being bad (although again, improving from "shockingly bad "3 years ago, to "not great" this year, IMO)
DS2 had some breathing problems after birth, and the care he received was exemplary - couldn't praise it enough.
things I'm glad I did/wish i'd known, in case these are any help to you -
join an NCT group/classes in your area - great for making friends and support for you and your DH - the baby shop BORN on Stoke Newington church st has lots of details of various things going on around Hackney
be prepared for things not to go as your birth plan (although I agree absolutely that it is good to have one to explain your general wishes) and don't stress out if it doesn't go to plan, it was disappointing not to have a vaginal birth etc, and i did feel a bit of a failure, ridiculous as having two lovely babies safely is the main thing
if you intend to breastfeed, identify a bf clinic near you, bf assistance is still shockingly bad in Hackney, the much-praised bf counsellor in hospital was away when both my babies were born it was a disaster with DS1 and if I hadn't heard of Ruth at Highbury Grange GP surgery I would have been stuck again with DS2 - bf isn't as easy as it is often made out to be for some, and I and lots of people I know really struggled
good luck to you
