Elkhorn Angani 81

Sun Valley - Idaho

Elkhorn Angani 81 is a cozy and clean condo located in Sun Valley, 300 metres from Elkhorn Village, offering views of the mountains. It's perfect for a weekend getaway for two, with all the necessary kitchen tools, a refreshing pool and immaculate grounds. It's close to town and amenities like the pickle ball courts, bus stop, parking, and swimming pool are all within walking distance. However, the bedroom is a bit dark due to marginal lighting, and the photos misrepresent the actual place. It's also expensive and there are hidden fees. But it's well mapped out and overall a great place for a weekend stay.
