We recently stayed in Les Jardins D'Issil as a group of 30+ people to celebrate a birthday.
What a wonderful weekend we had. The owners, Patrick and Ghislaine were wonderful as were the staff that worked tirelssly to make our stay so enjoyable. The place itself is in the middle of nowhere, but only 20 minute taxi ride into Marrakech. Its a calm peaceful oasis.
The rooms were beautiful, all decorated in authentic Morrocan style.
As previsouly commented on, there isn't any chouce when it comes to food, but I didn't find that to be a problem. The food was tasty and wonderfully presented.
I would definitely return here, either as just adults or with children (great pool!).
