Entrance to the hotel is located in the terminal building/SkyCity, meaning you do not need to leave the airport to get to the hotel. Clean, fresh rooms with Rituals dispensers in the bathroom. Comfortable beds and wide-screen TV. Excellent hotel breakfast buffet in a spacious restaurant.
My only complaint would be the one-ply toilet paper. I stayed at a 2-star hotel in London and in Amsterdam before coming to Stockholm, and they both had better, softer toilet paper. Given the high quality schampoo, conditioner, and soap dispensers and the lovely, big towels provided, I'm surprised that they appear to have saved on the quality of toilet paper.
