We stayed at SeLevi for 4 nights in February, and had a great time.
The lodge is great, with room for 6 people. It is fully furnished. We loved the large drying cupboard and the jacuzzi bath was great after walking around in the snow.
We got to everywhere easy, no more than 10-15 mins with children. But also in a nice quiet area. Bonus, we also saw the northern lights just from the turning into the little road/lane the house is on.
Would definitely recommend.
