Bit late on this sorry but wanted to add my bit.
Don't know much about llandough but had both DC in the MLU in UHW.
Many points have probably been mentioned in other posts but here's my experience.
Was a very positive experience both times.
Was offered anti-natal class in the actual MLU at 36 weeks. It was a one off 2 hour session. Guided tour of of the whole place, all the on-duty MW came to chat to us....very informal. There were 4 couples in each session and lots of tea and biscuits
MW gave us all a go of the gas and air (DHs included!)
It was very clean and tidy, midwives were very, very lovely. Had a waterbirth with both DC. Very good experience.
After an hour or so after each birth, went and had a shower (MW waited out side the door to make sure I was OK!), washed my hair, put on some clean PJ and jumped into bed with DD in the cot and DH by my side. Double bed in each room with en suite bathroom. Lovely thick quilt, not usual hospital blankets (minor but it was very much "hotel like" rather than hospital!). Mini TV at your bedside with radio (think you had to pay for the TV channels though).
Very good breastfeeding support. DD1 was ok but DD2 was very difficult to feed. MW sat with me for hour at a time and helped get feeding established, including hand expressing. She was very supportive and patient.
No visiting hours, so family and friends are free to come when they/you wish. MW always run in by you before letting them in, so no need to worry about unwanted visitors.
MW need to buzz people in and out so it's a very safe and secure unit and baby is given an electronic tag on his/her ankle at birth. Sensor by the door which sets off the alarm if baby crossed the door way.
I had such a very wonderful, happy, joyful experience there.
I was gutted to leave
