We stayed for the month of August and loved it. We have 2 young children and our guests ranged from grandparents to other families with small kids, and everyone loved the house. The kitchen is big, the bedrooms are nice, especially the master bedroom, and our guests all loved the pool / guest house and the tennis court. The owner was very responsive whenever we had questions, and the house and property [including the pool and tennis court] were well-maintained.
We hired a chef to cook dinners most nights for our big group, and the chef loved the kitchen for its size and all the dishes / pots they needed.
We spent many nights outside on the patio, enjoying dinner under the heat lamps and then sitting by the fireplace and making s'mores with the kids.
We would definitely recommend this house to friends looking to rent in Montecito.
