We stayed in July. It's hot, even in Keystone. Only complaint, no air, no ceiling fans. To owners: simple, spend $400 at Lowes and buy a portable air unit for the summertime. Most people won't even use it.
Everything else. Praise. Unit was fantastic and Ryan was easy to deal with.
Perfectly furnished. Comfortable and fun. We'll be back for sure.
Keystone is a perfect location. 12 min to Breckenridge, 4 miles to Dillon. It's off the highway, therefore quiet. First night there, deer in the parking lot. Best was 19 miles backpack to Bierstadt Peak or 32 miles by car. 1.5 hour drive to Rocky Mountain National. 40 minute drive to Vail.
Wildlife everywhere in summer. Keep your eyes on the road.
