We had x5 families stay at Sheerwater for a week over Christmas. I was a little worried about the no aircon situation, especially with little children/babies/grandparents, but it was absolutely fine; aircon was not needed! The house was beautifully cool, and the airflow was excellent. Comfortably houses large family groups with enough space to escape for some quiet time when needed! It was very relaxing, and the house is huge. We never felt like we were in each other's pockets. Loved not having to pack the car up to get to the beach with the kids - it was all within walking distance/kayak distance! Everything was spectacular, highly recommend. Sue the host is extremely lovely and very quick to respond, making our stay even more enjoyable. Couldn't give this place enough praise - five stars!
