We arrived at El Kahena planning to use their campsite for a night, or maybe two. We left after four nights in the hotel.
Ismail and Sonya are wonderful hosts, naturally friendly and enthusiastic. Ismail gave us a personal tour of the local area, including places we would never have known about on our own - a real insight into Tunisian life. The hotel is superb value for money. It's a good base for visiting Sfax (about an hour away), El Jem or Mahdia - all very worthwhile destinations. El Louza itself isn't exactly on the beaten track, but it's a pleasant little town. Jebeniana is close and has most services you're likely to require.
It's an excellent stop-off on your way south.
