here is a great tour inside the aircraft with 1 of it's pilots (in russian, but with a comprehensible English subs):

I knew it carried its whole crew with it, but the cabins are almost a little hotel, two kitchens! Three sleeping quarters! And that's all just tucked into the parts that aren't used for cargo.
I got a few good chuckles out of the back-and-forth, just from the subtitle, I'm sure it's even better if you speak Russian. Well worth a watch, thank you for posting it!
