We spent 4 wonderful days at Peter's property. I would say all 8 of us had a great time - being able to soak in the hot tub after a day on the slopes is just fantastic. The place also has a great living room space with a fireplace and plenty of board games.
My only two notes are: as the description says, the place is well setup for two families+kids, if you have 8 adults, and especially taller ones, plan your bed assignments! We had a few bed swaps but it all was fine in the end. Lastly, if you are planning to make big meals for a large group, you might want to bring and extra pot/pan, the kitchen has lots of utensils and stoneware but could use some extra cooking pots/pans. Not a big deal, just something to plan for.
