I had an excellent one week (wk13) holiday in Ylläs, http://www.yllas.fi, situated in the Finnish Lapland.
Here's some basic data of Ylläs:
61 slopes (53 km)
29 lifts
Longes slope 3 km (463m)
Weather for the whole week was sunny. Temperature dropped down to -14 celsius during the night and was around -5 celsius during the daytime. Slopes were in excellent condition and there were around 100 cm of snow.
