Hi , it is quite small, it has three small rooms as Mommy2ash said I. It was run last week by Elodie who was French , but spoke English quite well.
Children can be play there with parents or left , signing in and out forms to be completed. You have to be Hotel Guests and they prefer mobile number to be left if you are leaving the hotel.
We left ours for 30 mins one evening for a quiet drink and I played with my little girl for another half an hour on a different evening. When we were there it was quite quiet, I dont know what the staff ratio is or if once they have so many children without parents they cant allow any more to be dropped.
There is no charge
It is on the ground floor ,very near the Pool which itself is in its own room with double doors overlooked by a Spa reception desk which was always manned when we were there. I didnt have any safety concerns the children seemed to well contained in the rooms.
