Pre-kinder or Montessori schools in El Golf area? (Santiago de Chile)

We arrived in Santiago and are looking for a pre-kindergarten, montessori school, or the like in Las Condes within walking distance of the El Golf area. Our daughter is 3, and we are looking for something half-day so that she can learn spanish and meet some new friends. We will be living near my office in the El Golf area, and since we will be trying to stay without a car, we prefer something within walking distance. Any assistance or recommendations are appreciated.
