Can i fell asleep during the night? how safe it is?

You can sleep very nice and not much noice, its a safe place to take a good nigth sleep.

I sleep there all the time. Just as safe as any rest area.

Sure It is

You can sleep the night at any rest area. I have not slept at this one so I can't speak to overnight safety, but I would assume it is fine if it is anything like daytime.

Good and safe place.
