Hi
I've had both daughters at QE in the last 3 yrs & know several people who have also delivered there. I have nothing to compare it with but on the whole there are many things to recommend it by. It has a special baby care unit on site which is brilliant should the worse come to the worse and you need it, the delivery suites were large, birthing balls, pools etc, very clean.
As ladybee says, the wards are busy. The care in the delivery suites was fab (all midwife care upt to and after - I was registered with Orchard midwives) but it is a challenge for the midwives to give lots of time in the wards after although I did get lots of BF support (and there are other ways you can also get bf support after).
Considering it serves a large portion of a very diverse part of SE London, it does a good job and there is a certain amount of snobbery around QE that is best ignored IME. It is midwife led and although both times I ended up being induced due to being overdue (and DD1 birth being v complicated), I always felt in control and consulted.
The most important thing is how you gel with your midwife and if things aren't going well, be assertive and ask for another.
I do agree that the food is bad although I'm sure no hospital food is nice. But you'll either be so ravenous you won't care or you get something nicer shipped in from outside.
There is a lot to be said about being close to a hospital and not having to contemplate central london traffic when the time comes which is why I ruled out st thomas etc. There always the option of birthing centre (I think one in docklands and tooting) or private midwife but that costs!
