This is a gorgeous house in Tahoe Donner right by the Adventure Center - great hiking and riding trails and lots to do! There is plenty of space for a group of 10. It was super clean and the kitchen was very well stocked. It's managed by a professional company, so has good towels and nice toiletries provided. There are multiple documents with instructions so make sure you check the various places for e.g. check out instructions. Also, they make you sign a very strict contract (after the cancellation period has passed!) that lays out a bunch of fees for things like having an 11th person walk on to the property during your stay. I would suggest you ask for it up front before you lock in the reservation!
