Very spacious - there were 8 of us, and we could probably fit two+ more people without noticeable discomfort. Spectacular views, very solid and attractive modern construction. The Old Town is within 2 minute drive/10 minutes walk.
Needless to say - the house is fully stocked with sufficient dinnerware, stemware, silverware, and other -ware for everyday living. On our days of eating in our cooks were not wanting in any utensils/pots/pans needed for cooking. Furniture is abundant, smartly placed, comfortable.
On the first day there was a minor issue with the fireplace, which was promptly and efficiently resolved within less than 12 hours.
Of course, nothing is ever perfect, so I can find peeves if one looks hard enough. On balance, though - for the right price this is a superb rental for a group of 8+.
Some hopefully useful pointers: please seriously consider having a 4x4 vehicle, as getting to the property involves driving up and down the streets in places somewhat steep. Any insignificant amount of snow on the ground, and getting there in a regular drive car would be a challenge.
We tried to mostly ski Deer Valley, so have not used the proximity to PCMR; so can't comment on the "walk-to slopes" feature.
TV in the family room has HDMI input, WiFi appears to be ISDN, so maybe somewhat slower than what we are used to, although more than adequate for 99% of possible vacation needs like browsing and emails.
