With my first pregnancy I shared a room and it was terrible! She kept farting and it stank, then she would just let her baby cry and never fed it, spoke a different language (no dramas) but when her visitors came there were heaps, all the time and I went home as soon as I could.
2nd time I shared, she was in the room at 3am and had a c-section so couldn't do much for the baby. The first 2 days the curtain stayed shut, but then the nurse was a b!tch to me so once that nurse left she asked if I was ok. We got on really well for the next 2 days before I left. 3 years later and she still post on my wall to say happy birthday to my son, but since I moved back to Sydney we don't really talk much.
You just roll with it though, you aren't there long.
