Is the private pool easily accessible to small children? Is there a door or some kind of barrier from the room?
The villas are designed in segments. To go from one segment to another (e,g, from the kitchen/living room to the bedroom) you open a door (which can be locked) and step outside for a few meters. That open area has direct access to the pool. If you are concerned about letting small children run around in the villa without having access to the pool, this is not the place for you. Wonderful place, but you definitely would need to watch your children closely if you were concerned about access to your private pool.
