Hi. I'm due to give birth in QA hospital (it's in Cosham, so at the north side of the M27) in the next few days (am 39+4 today).
I had a tour a couple of weeks ago. It is very modern and clean, all the rooms have bathrooms - so no wandering down the corridor in your birth t-shirt...or whatever.
At QA there is a consultant-led unit and a midwife-led unit. In reality, the two units are next door to each other, so the only real difference is that the midwife-led unit is staffed by community midwives etc. Obviously, if you needed the attention of a doctor etc you are only a corridor away.
In the midwife-led unit there are 2 rooms with birthing pools. In the consultant-led unit there is one room with a pool (might be good if you would like the pool, but want to be in a consultant-led unit because of your previous experience.) Pools are subject to availability - as in most places.
Post-natal wards are either 4-bedded rooms (with bathrooms) or private rooms (with bathrooms). I think you may be able to pay for a private room, if it's something you wanted to prioritise.
The midwives told me that what is now in St Mary's, Portsmouth, is just a midwife-led unit. I gave birth to dd1 in the consultant-led unit when it was there (2 yrs ago); so am not sure if they've refurbished it to make it into a new midwife-led unit.
I live in Gosport, so my nearest midwife-led unit is Blake's. After I gave birth to dd1 in the consultant-led unit, I transferred back to Blake's and stayed there for several days. I had wonderful care there and managed to establish breast-feeding there. Also, dd1 was jaundice, so it really helped rather than going straight home.
Just mention it as it may be an option i.e. if you go for the consultant-led unit in QA, you can then transfer to your local midwife-led unit for after care.
Hope all goes well - sorry for rambling!!
