This was a great spot for our family trip to the Colorado mountains and had enough space for Grandma, our family of four, 2 cousins and an uncle. The location was great - near Grand Lake and very close to the entrance to Rocky Mountain National Park - and the house had cozy charm and nice amenities. The kids enjoyed the ping pong table and the arcade games, and everyone enjoyed eating on the deck, the hot tub and the propane fire pit where we roasted marshmallows in the evening. When I needed assistance, the owners were quick to answer texts and provide help.
There were a few minor drawbacks - the lake next to the house is for private residents only, which was disappointing & not clear before booking (it's calmer than Grand Lake and I would have liked to take the kids out on it), and although the washer and dryer are there for use, there isn't laundry detergent provided. I also had trouble tracking down conditioner. So, if you do decide to stay here (and I recommend it - as I said, these are minor), I'd recommend bringing your own.
Overall, we'd be delighted to stay here again for a future family trip and have already recommended it to another branch of the extended family.
