Stayed here over New Years and had a great time. The condo really has 3 bedrooms, although the "bunk room" bedroom is small it worked well for two kids in the bunks. The location is close enough to River Run that it's faster to walk than to drive, as my daughter proved a couple of times. One thing that wasn't mentioned in the listing but was a HUGE bonus was the included use of a locker at the River Run Lodge. It was great to be able to lock up our skis, boots, and poles every night and walk back, then in the morning walk over and change into ski boots and get all our gear.
Definitely recommended and we'll try to stay here again next time we ski Sun Valley.
