Pros:The hotel is located less than 5 minutes from Arlanda Airport. The hotel offers a FREE shuttle to & from the airport! They will pick you up FROM the airport 24 hours/day (just call them and they will pick you up) They will drive you TO the airport 24 hours a day, with trips available every 15 minutes (just let them know in advance, so they can add your name to their log-book). They will even take you to/from the airport if you are planning to spend the day in Stockholm (catch Express Train at airport, and/or take bus & train (slower, but cheaper) There is a VERY nice buffet breakfast included in the price (various breads, cheeses, cereals, fruit, eggs, juices, coffee, tea, etc) (also meats, but I'm vegetarian, so...) They also offer a fairly reasonably-priced (considering that Sweden is relatively expensive) dinner menu; just the salad bar option was very filling and tasty. The hotel itself is very "minimalist"...you get a bed, shower, toilet, sink, and place to put your bags, and that's about it!
Cons:Rather expensive to get "to and from" Stockholm. I would recommend staying here if you get in on a late night flight and want to go right to sleep, OR if you have an outgoing flight and want to minimize stress by being close to the airport with a free shuttle available. If you just want to visit Stockholm, there are cheaper options available there, with no need to commute.
