We rented this cabin almost at the last minute, and couldn't have been more pleased. The house itself is beautiful and airy, with high ceilings and huge rooms. The accommodations were very nice, and one of the co-owners. Mike, was accessible and helpful at every turn (the other owner is probably just as friendly, I just never spoke with him).
One thing that Mike highly recommended was a 4-wheel drive vehicle, which I think would be indispensable in snowy conditions. The cabin is located about midway between Keystone and Breckenridge, you'll need 4WD traction to get up and down those hills. But the trip is actually kind of relaxing, and the peace and quite of the cabin's surroundings make it well worth the effort. Plus the views are spectacular.
Overall, an excellent experience. We definitely want to come back.
