Ferienwohnungen.
Generally a good deal if it's several of you, it's self-catering, and usually a fairly spacious apartment with a full-ish kitchen.
Also, mid-Feb. is the school holidays, expect utter chaos on the slopes. You're far better off being on either side of February, in other words you're better off visiting mid-January, or starting the first week of March. Otherwise, it's a rotating door of schoolkids, combined with sky-high prices and full accommodation.
