We stayed at Art Riad for three nights in the summer and thoroughly enjoyed it. The riad is so small and cosy and the owners so warm and hospitable it feels like you are staying at a friend's place. Altogether a lovely experience and way better than any five star hotel. The nearby beach is also lovely and sandy.....and no crowds!
I would just recommend that anybody booking to stay here makes sure they email the riad directly to get hold of a map: the riad is in the middle of the medina (it's a maze!) and without the map, you'll never find the place....but it's a fun challenge looking for it.
