We stayed 1 night in an Aurora cabin during January. Unfortunatly we did not see the Northern Lights, as the weather was too cloudy, but we still enjoyed our glass roof cabin experience.
The Aurora Cabins were very modern inside, and the glass roof was heated, for clear viewing of the sky. These cabins are facing the North, to maximise your chances of seeing the lights.
The Star Artic Hotel resort is located on the top of a big hill, which offers really good views over Sarriselkä and Inari. The best viewing point for the Northern Lights (i.e. the Triangulation Tower) is only 300m away from the hotel.
We ate dinner at the Star Artic restaurant, which was fine dining & delicious, but a little more pricy than in-town options. Staff were very friendly. Buffet breakfast was included, which offered a good range of options.
Checkout was at 12noon which was great.
A good tip is to ask reception staff to book you a cab for the trip back into town 24hrs in advance, as you will get a cheaper fare, i.e. 10 euros instead of 20 euros.
