Sounds very similar to us, although we weren't in for quite as long. The shared ward was a nightmare. So loud and so busy. I remember thinking 'everything will be a piece of piss compared to this', and it has been. Those first few days were hellish.
The hospital were good on the whole, but trying to get out of there was such a mission. Most of the midwives were contractors, so you're begging someone to let you leave, then they disappear. Felt like I was going round in circles. So very frustrating.
