"If you need to be by the airport, I think Jumbo Stay STF/IYHF is super awesome: it's a converted 747 with singles, doubles, and 2–4 bed dorms, and the standout is the cockpit suite with a private bathroom (starting at 1,850 SEK). It's open 24 hours, has an on-site restaurant and bar, towels and linens are included, and the smaller dorms (2–4 beds) mean you won't be overly crowded." - Matthew Kepnes
