Rock N Play @ night?

I've read so many controversial things about babies sleeping in a Rock N Play at night. We have a co sleeper for in the bed, but she absolutely hates sleeping in it. Plus she spits up at night and I'm scared she's going to choke. We put her in the Rock N Play last night for the first time and she slept SO well which in turn made us sleep great. And she didn't spit up at all. When I was in the hospital I asked one of the nurses if it was okay if she slept in the Rock N Play and she said she didn't see why not. And a lot of people have said their babies sleep in them at night and are perfectly fine, but then I see some people say it's awful for them to sleep in the Rock N Play. I also ordered a bassinet for her to sleep in so I will try that when it arrives on Monday. What are your opinions on sleeping in the Rock N Play at night? I just need some peace of mind... I don't want to be a terrible mother for letting her sleep in it.
