I have just returned from a week-long stay in Chalina estate in Canggu with my entire family of 9 adults and 7 children (aged between 4-18). I booked this villa through Luxury retreats. The handling of my booking with Luxury Retreats was average with some major miscommunication. I wouldn't recommend them.
The villa itself: gorgeous grounds, lots of space to play or find a quiet spot to oneself. the pool is the highlight, the kids thoroughly enjoyed it. Pool toys would have made it even better. location is a good, 20-min drive to Canggu shops and 45min+ to Seminyak, if you don't mind being away from the action.
the onsite staff were friendly and courteous. food prepared at the villa was average: nothing outstanding, better food can be found outside the villa.
Chalina could improve with new pool towels, updated furnishings (tattered and ripped cushion covers), boutique toiletries, current reading material and DVDs.
One more thing which was noted by many in our party, ALL the rooms are very dark. mood lighting is nice but when you can't see what is right in front of you, it might be a tad dark.
