The Springs, Extra Large Condo. Cool winter deals!
The condo was perfect for our purpose. We came for a family ski trip and the location was perfect. Easy access to the gondola and having the ski lockers was very beneficial. The condo itself was very clean, plenty of towels, good WiFi and comfortable bedding. We didn’t really utilize the game room ...

John's condo is a fantastic one bedroom in the heart of River Run. It's a short walk to the gondola with restaurants, shops, and a market just feet from the property. John was a gracious host who repeatedly checked in to make sure everything was okay. Easy to give this one five stars.
