Overall our experience was positive. There were a couple of minor issues which I'll list below.
Location: Great location for summer. Since we had no need to be near any of the lifts, this location allowed easy access to shops/restaurants and generally driving all around town.
Bedrooms: We had 6 people which comfortably fit in the cabin. Kids took the loft, and adults took the bedrooms. Plenty of room for all of us.
Amenities: The place had everything we needed for cooking and eating together. Outdoor grill came in very handy too.
Issues: We were in mammoth during a record heat weekend. Most places in mammoth don't have AC (just this like cabin), but have ceiling fans to create airflow. The ceiling fan in the loft was non-functional, so all the heat trapped upstairs turning it into a sauce and not usable. We contacted management both via phone and on VRBO messaging and did not hear back for 24 hours until after we checked out.
