Jumbo Hostel (Stockholm Airport)
"Welcome onboard the worlds first Boeing 747-200 Jumbo Jet converted into an upmarket Hostel for the discerning traveller! Jumbo Hostel is only a ten minute walk away from the check-in counters at Arlanda airport, perfect for anyone catching an early flight and doesn´t want to get out of bed before dawn to make it to the airport in time. Now you can easily book a night at Jumbo Hostel prior to your departure for an extraordinary experience before beginning of your trip – as well as relaxation.The price for a hostel bed is about US$43, which is high for a hostel, but dirt cheap for Sweden. (Hostel beds in Stockholm itself start at about $30, without breakfast or linen like this one provides.) It's a good deal regardless of the venue!
"Jumbo Hostel offers 25 comfortable rooms with either two bed, three bed or also 4 bed dormitory style. All together, the hostel offers 74 beds; the most luxurious is to be found on the plane´s upper deck which boasts an exclusive cockpit suite with private ensuite bathroom and toilet."

Austin Powers, eat your heart out!
BTW: Here's another interesting hostel in Stockholm, aboard a sailing ship: STF/IYHF at Chapman
For the record, I should note that it doesn't matter to me whether I sleep in a 747 or a sailing ship, seeing as I will be unconscious most of the time. While the idea is cool, I don't feel any pressing need to actually stay there. The premium I am willing to pay for the privilege is very low—maybe $10 at most.
