I would advise that you take part at an information evening at the hospital. All questions concerning rooms, transfer to Uni hospital etc. should be answered there. Here's the link

Normally, you can have a guided tour through the maternity unit afterwards and make up your mind yourself.
Usually, the maximum stay is 4-5 days including the day of giving birth. If you're about to give birth 2012 they'll probably send you home earlier because of a change in the financial system. If you are having a cesarean or had a long birth you might stay longer than 4/5 days. Make sure to organise a midwife who takes care of you at home after birth
