Four families with our children rented this house for a week and we had a wonderful time. There was plenty of room for everyone, all of the bedrooms were air conditioned and comfortable, and the house was stocked with everything we could have wanted, including a great, open kitchen with a table and bar seating, plus a finished basement with a big TV and gaming equipment, and even a fire pit.
The owners were very responsive to our questions, and the house is a very short walk to a nice, quiet beach. We walked 15-20 minutes into downtown Hyannis almost every day, where there are shops, restaurants, and activities. The only negative thing I could say about the house is that we couldn't figure out how to lock the bathroom doors, so we kept the doors open unless someone was using them. We definitely would recommend this place and are hoping to go back ourselves next summer!
