I stayed there years ago; it was utterly dreadful - we actually left. Beware of hostels that are part of pubs; they often, ime, have very poor cooking facilities, so you are forced to eat in the bar (though you might prefer that anyway), and can fill with drunk arseholes (though you might want to be one).
This is more the sort of place I'd go for - I think I've actually stayed there, but can't quite remember. If it's making the most of conditions you are worried about, I'd still rather stay with a guide like Kimber or Fraoch lodge - guys like those will know safe routes when the weather is dreadful, and find snow when the hills look bare, so you can make the most of your trip. Conditions are so local; one side of a glen can be bare, the other waist deep in snow.
