The house was a perfect size for our large group. We are a softball team with a cheering squad, so at any given point, there were anywhere from 10-20 bodies in the house. It slept 12 comfortably, but could have easily slept more. With the large dining table and the stools on the island, we had plenty of seating for meals (including hosting a large BBQ). The outside area is spacious and, on warm days, can easily accommodate another 12+ people for meals. We never once had not enough seating.
The rooms were surprisingly quiet even with several people still hanging out downstairs.
Barry, our host, was friendly and gracious. He was very quick to respond to any needs we had, and we never had trouble getting hold of him when needed. He also checked in with us frequently to make sure we had everything we needed.
Will be staying here every year when we come out for our team trip. The house is a bit in the boonies, but conveniently near two major freeways, so we had no trouble getting to where we needed to be in a timely manner.
If you have a large group, this is your house. Plenty of parking, lots of sleeping space, several bathrooms, and a kitchen/dining area that can host large meals.
