Good points are the price and free delivery, and it looks quite nice. Strangely you get loads more screws and dowels than required- probably only used half. 
The main bad point is the useless instructions. There was a glossy colour section where you could actually see the photos, but the main bit was a poor photocopy. Also poorly written, in a random order, with bits missed out totally so a fair bit of guesswork is required. It's very difficult to build it in a small room. You will definitely need to buy extra brackets to attach it to the wall, as the vertical ladder design means the whole bed tips up and wobbles when you try and climb in.
