I had an NHS cubical for 1 day after ds then got put on the ward. If I could have afforded a private room I would have had one.
There are only a limited number of times you can re live the birth story of the woman in the next bed, especially when it gets more elaborate every time.
My 'neighbour' was a nightmare she kept hitting ds's cot with her chair when she kept shoving it into my space to give herself extra space. Her curtain was literally right up to the side of my bed as she felt claustrophobic and apparently as long as the new space she acquired was behind her curtain it was ok.
She kept going on about how little space she had I know the fucking feeling in my half size cubical love (i was in a corner space too to had a wall to the other side of me) when I moved the chairs back into her space she complained to the ward manager my curtain space was bigger than hers and asked to swap sides with me :/
Oh and she felt her ENTIRE c section but Was too brave to tell anyone as she wanted to be awake for her child being born - fuck off 
It was probably more annoying as I'd needed a crash section and then resuscitation in my labour as well as my uterus rupturing so being told in front of this gobshite I could no longer have children and listening to her whispering this 'gossip' to all her visitors. I had to listen to her bullshit for 3 days.
She didnt flush the toilet after a poo. Left dirty used sanitary towels in the shower and insisted her dh stayed overnight to care for the baby as she was too tired to, poor love
Everytime I got up in the night to go to the bathroom he tried starting a conversation with me as he couldn't sleep....

I would definitely Max out my credit cards to pay for a private room in future, not that I will be having more though.
