House run as essentially a hostel. Read all of the information, and look at the pictures, in the airbnb page for the house. All the information is accurate. We were very happy with the arrangements. The host is amazingly nice, and it was fun chatting with her and the Brits who shared the place with us. But it may not be for everyone. You need to be OK with interacting with others in a hostel type setting.
Some more specifics: The beds were comfortable. Plenty of hot water. The house was very clean. The house is 20 meters from the slopes (toward the bottom of the resort in case you want to linger to have a drink after the slopes close). Limited restaurant options in the evening; I suggest bringing up your own food for evening meals. Host arranged transport at a very reasonable price to/from Santiago. The dogs in the pictures live in the house. If you have any questions, ask the host, she is very nice and knowledgeable.
