stayed at the St Lukas this January 2013
We had 4 in the party and had 2 rooms, both had a nice balcony and were clean, not large but not small either (seen much smaller in France chalets for example).Believe the house does have larger 3 bed rooms if you are lucky.Both had decent pressure showers/bathrooms ensuite.
Food and wine was good and we liked the position, about 400/500m away from the action.The free boot and ski storage at the lifts made for a nice walk in the mornings.
Overall, good chalet with a nice feel in a decent setting. Enjoyable break.
