You will get good and bad stories wherever you go.
I went to st Mary's with ds2 last July (2011), and hoping to have ds3 next week in Salford royal community midwife led unit.
I didn't like st Mary's for much of it.
I even put in a formal complaint about one very bad attitude young mw.
Student mw told me I was 8cm, but I was actually 5cm.
One young mw was texting the whole time she was in the room with me and dh (pool room)
One mw just have the impression she wanted to be somewhere else and couldn't be bothered.
When labour didn't progress, after over 24 hours of being there, me begging for an epidural, 3 lots of diamorphine, 3 times in the pool, god knows how much gas-they decided I needed help 
The last 3 hours of me really struggling with pain and exhaustion I was simply told if I didn't get this baby out I would be out on a drip. No support, no nice ness about anything, literally I was left to it.
Then I ended up having an emergency spinal block, prepped for c section, thought they quickly try ventrouse first and whipped him out.
After care was quite good though. And in theatre I felt very safe as there were loads of people around.
Food was rank.
But everywhere was nice and clean and i got my own room.
