We stayed here in August - which is great if you want to get away from it all (which we did)...don't expect too many late nights in Luosto! The cabin is lovely - great big kitchen, really comfortable living areas and a fire and we loved the wet room/sauna/hot tub. There were only two of us so we had loads of space, although probably in an ideal world there'd be a double bed or two rather than singles, but we found singles to be the norm in Scandinavia. It's about 10/15 mins walk to the shops - there is a small convenience store in Luosto. To go to a bigger one it's about a 15/20 minute drive to Pyha.
Obviously hard to say what it would be like for skiing, but the accommodation was great and the service received from the owners and the local travel agency was excellent too.
