I spent one week in Eden Village Djerba Mare - it was a pleasant stay: very friendly staff, great choice of delicious food, the room and the hotel overall very clean. Nice sandy beach.
We had a triple room - twin bed and sofa as an additional bed,which is suitable for children,but we had worse than this.
I would recommend this hotel to everyone!
My tips: rent a quad and make a trip to 'Blue Lagoon' . In walking distance there is a nice Café at the round-cross where you can sit on the roof-terrace.
Disadvantage: the only problem,which could be felt as unpleasant: dirty public areas - rubbish everywhere,but it is not the fault of the hotel.
