Great place with mountain and river views 3-4 miles from the Breckenridge Town center. They have a few shuttle to the town. We were able to walk one way and then get the shuttle the other way, which was nice. The walk was mostly along the river. The rooms were very comfortable with a kitchenette, sitting room and bedroom, though sitting room has no windows for natural light. Nice big screens in both rooms. They do not serve any free breakfast and nothing hot, though there is a bar for drinks and bar food.
