This bed is pretty straight forward to put together, takes about 3-4 hours. Looks cute. Don't worry that there are several left over holes in it that don't get screws or pins. Weird that there's random holes.
The smell of the packaging and the bed itself is OVERWHELMING! We bought this bed for our daughter who has severe allergies and she has broken out ALL OVER her face and arms just from the fumes that are emitting from the bed. DEFINITELY open a window while you're putting it together and wipe down each piece before you put it together.
Just as a side note to other parents, the height of the bed is going to make it difficult to get underneath it and clean up your kids' toys and such. I wish we would have gone ahead and gotten a higher bed. This isn't a design flaw or anything wrong with the bed, it's just a low space. 
All in all we're pleased with it. We just hope the fumes will die down very soon.
